no pooya you are wrong there are other options

other options are
taproot devs made a promise that taproot witness would look like a single signature on ~80bytes
and so keeping to that promise they can release a client we all upgrade to. that from block 7xx,xxx all taproots relayed at unconfirm are only 80byte limit witness. and if they get into a block after 7xx,xxx they would reject a block that breaks the rule


that way it does not stop proper use of taproot, nor does it cause a re-org, nor does it cause the stuff you speak of
it actually enforces the rules that were promised. by strengthening consensus rules and tx format policy as should be the case all along
