Why knot just limit the Tabscript size like it was with SegWit v0?

Oh wait Luke already opened a PR for it and core rejected it.

There was NOTHING stopping inscriptions from existing pre-Taproot at SegWit v0 except the script size limit policy (filter).

The only reason inscriptions use Tapscript is because there is no size limit filter. nostr:nevent1qqsq4m8es9z2ylyy4et9ys2qysv79zumsjy9maqhcv9wyqvrkjkltsgtsgxcf
