Yep, many games give you some kind of reward or recognition for things.
The first example on Stealth Run is this
- Final Ninja 1 and 0 give an end-of-level point bonus for not being seen.
That is a legit example of a Stealth Run, as would be an achievement or a section(s) of gameplay where its game over if you are ever seen like Metal Gear Solid's Extreme difficulty.
The second example
- Pacifist runs are possible in many levels throughout the Jedi Knight series of games, popular amongst some enthusiasts who enjoy following the Jedi Way, especially once one attains the ability to disarm or to mind trick their way through the countless hostiles. Averted in some levels thanks to a stated mission objective. Clearing a level is also an unstated event trigger late in Jedi Outcast. Ergo, a disarm-only approach can require very un-Jedi-like measures to proceed.
People who do these on streams and such are part of a community and that is different from the game itself. That should be linked to the community or their streamer page.
No, that stuff should be part of the currently existing pages.

Yeah, the division was established two pages ago. We are splitting our subject of discussion in three, In Game Challenge for anything that gives you an achievement or better, Self Imposed Handicap to rescue in universe examples and Community Challenges, which are the tropable remainder, and delete the rest.
Challenge Gamer needs help, too; it should probably be restricted to In-Universe Examples Only, though there are quite enough of those.

Speedrunning Achievement should probably be its own trope, honestly. I'll probably TLP that later.
