I would accept it, if each Ordinal would require including OP_RETURN at the beginning of the TapScript, to prevent them from being pushed on-chain. In that case, they could still be moved by a single Schnorr signature. Or, even better, creating a new Ordinal should not require sending them to Taproot at all, but just the R-value of a signature, from any address type, should be sufficient to make a commitment.

Which means, if some user has some legacy address, then it should be possible to sign a regular transaction, and then, R-value of that signature could contain some Ordinal.

Also, Ordinals should support scanning the chain in a similar way as Silent Payments could do. Which means, users should not be forced to upload data, if they were already uploaded in a different form. For example, there was a user, trying to upload the whitepaper, even though it was already done, and it was wrapped in a multisig in some old transaction. Which means, Ordinals should allow scanning the chain, and discovering old data, without reinventing the wheel, and forcing users to post that data again on-chain.

Another thing to address is the content of each Ordinal: some people tried to create something like NFT. In that case, the uniqueness should be enforced. And by scanning the chain for similar data, it should note that "hey, the whitepaper was already pushed by someone, in a multisig, long time ago", so the Ordinals protocol should prevent users from uploading the same data again, and again. Because in some use cases, like NFTs, it could be misleading.
