This is usually the part where I'd ask a follow-up question about some weird edge-case scenario, but I feel like the rule as written above is straightforward and non-punitive for good-faith storytelling devices.

If you re-wrote an old RP from a different character's perspective and used bits from the old RP to set the scene as such, that would be sufficiently transformative to constitute a new piece. Even if you did a 80s sitcom-style clip show, where you took some significant bits from your old pieces, it could arguably be transformative in a way that juxtaposing these new pieces might evoke some different meaning.

Buuuuuuut copy-pasting an old story with minor edits is pretty obviously bad-faith RPing, designed to dodge having to write as much in a cycle.

All in all, makes sense to me!
