📝 Original message:Firstly, a minor point is that your proposal is a soft-fork, not a
hard-fork.
But more importantly, adding limitations on OP_RETURN transactions is not
helpful. Users who want to embed arbitrary data in their transactions can
always do so by encoding their data inside the values of legacy
multi-signature scriptpubkeys (pubkeys can be generated without knowing the
private key in order to encode non-key related data). Not only can users
do this, users have done this in the past. However, this behaviour is
problematic because such multi-signature "data" scriptpubkeys are
indistinguishable from "real" multisignature scriptpubkeys, and thus must
be kept in the UTXO set. This differs from outputs using OP_RETURN which
are provably unspendable, and therefore can be safely omitted from the UTXO
set.
Thus, given that it is otherwise impossible to stop people from putting
arbitrary data values into their transactions, then we rather encourage
people who are going to encode their arbitrary data in transaction to use
the OP_RETURN outputs in order to avoid UTXO bloat.
Also, as it stands, fees already nudge various participants to consolidate
their data in the way that you suggest they do.
