Can DebutQueue fit in with EarlyBirdCameo and character introduction tropes

When watching a Live-Action TV series (Police Procedural as an example) can Debut Queue have any overlap with Early-Bird Cameo as a "sneak peek" of a character, and also would these tropes apply:

• Remember the New Guy?: The new ADA, Jane Doe was introduced in Season 1, Episode 12 (of 24) but we saw her uncredited in Episodes 1 - 12. Word of God is she was there since the beginning.
• Chuck Cunningham Syndrome: The new DA, Jenny Smith, just disappeared with no explanation.
• Loads And Loads Of Characters: There's 44 characters in the show, and all get listed in the OBB as "Starring" with no Fake Guest Star credits.

Equally could the same show have these for new characters:

• Villain Decay: One recurring villain introduced was once a prolific car thief but now he's given up on car theft, and decided to redeem himself doing talks in schools about how joyriding isn't fun, used to deliver an Aesop. The Villain Decay sets in after three episodes. (The character's not a Big Bad though).

• Fake Guest Star: We introduced this character but the actor isn't certain if they'll commit after their contract expires, so we may recast the role (would this be a Justified Trope example for this?)

• Written In Absence: Due to the actor being in a motorbike accident, we're going to write out the character for a while that we introduced six episodes ago in Season 1 but she'll be back when she's recovered in Real Life. However, she'll still be there... in pre-recorded flashbacks and archive footage.

• Temporary Substitute: The main characters (an Expy of Benson and Stabler) are in a DC Cinematic Universe film and a comedy, so they can't be here this week. We'll give you a new duo for an episode who are similar but not the same to them.

• Not Named in Opening Credits: It's a tentpole production with actors such as Emily Bett Rickards, Scarlett Johansson, Diane Neal, Clark Gregg, Daniel Radcliffe in the cast, and there's Loads And Loads Of Characters (44 in total!) but we can't list everyone in the OBB each episode so we'll have to list some in Closing Credits but does that qualify as Fake Guest Star?

Am I correct about these introduction tropes?

• Remember the New Guy? doesn't apply if the character has been shown previously, even if just in the background.
• Chuck Cunningham Syndrome is when a character ceases to exist in the continuity. It doesn't really matter how long they were there before, other than there has to be an expectation that they stay on the show, since otherwise you could say the same about any old bit character.
• Loads And Loads Of Characters probably applies with that many characters. It depends a little on their prominance, since they all need to regularly appear.
• Villain Decay needs more context than that. Switching sides isn't in any way a qualifier or even an indication on its own.
• Fake Guest Star needs to appear long enough to be functionally a regular cast member. That's probably around most of a season at least, and continue being called a guest star after that.
• Written-In Absence I'm not sure about, from the context given.
• Put on a Bus is when a character is written out without a specific intent to bring them back, but they're not written out in a way that they can't be brought back if wanted, like if they're killed off.
• Temporary Substitute can apply even for new characters.
• Not Named in Opening Credits is for avoiding spoilers. If there are just too many to name, it doesn't apply. That bit about Fake Guest Star only applies if they're billed as guest stars, not if they're omitted completely (which means those two tropes are mutually exclusive, unless the guest billing is post-episode).
