I actually heard about that theory before. Granted, it was from a quite hateful article about the show, but I think it's still an interesting theory.
The analogy is that the Cluster represents an unwanted late-term pregnancy that would kill the mother (Earth) if it was born (formed). It's a bit of a moral quandary if you look at it that way. Peridot wants to destroy (abort) the Cluster to save the Earth because she doesn't see any worth to it. But Steven has a reverence for all life, regardless of origin, so he begins to regret trying to destroy it. To him (or at least his subconscious [which may or may not be Rose]), the Cluster doesn't deserve to be destroyed just because it will unintentionally bring harm. So, he finds a middle ground between letting it form and destroying it; putting it in stasis (i.e. bubbling it). It's a pretty fair analogy from my point of view.
The article critiqued it, saying that since that middle ground doesn't exist in the real world, it's sending mixed messages to the audience at best, and advocating pro-life to an extreme extent at worst. So either this is merely someone seeing subtext that isn't there, or a case of Unfortunate Implications on the show's part.

I'm not a fan of filler, but even I think that's unfair to the episode.
It was cute, had some interesting development for Onion, and showed the show's transition from Summer to Fall.
As a non-plot/non-Gem episode, it's a lot better than some other ones.
