I think it's perfectly fine for someone to have a propritary extension
to PSBT that isn't going to work right unless used only between their
own stuff or need a translator to talk to ordinary PSBT stuff.
For that purpose, having some kind of versioning field that you can
use to indicate what weird PSBT dialect you're speaking might be
helpful, if only to allow for more reasonable error messages.
