This has been a question before, and the answer has often been “maybe in the future”, so I’m asking again.
Essentially, is there any plans around supporting parsing of uxml and uss at runtime? The typical use case would be something like fetching in-game update notifications like a lot of games have in the main menu, without having to deal with the complexity overhead of packing stuff into Asset Bundles. I can also imagine fairly interesting reflection-like usecases for building UI stuff on the fly.
I understand that this would incur a non-trivial performance cost to use, but we can work around and/or live with those. I think the value of this would far outweigh the downsides.
