Since Taproot was activated, we no longer need separate OP_RETURN outputs t=
o be pushed on-chain. If we want to attach any data to a transaction, we ca=
n create "OP_RETURN <anything>" as a branch in the TapScript. In this way, =
we can store that data off-chain and we can always prove that they are conn=
ected with some taproot address, that was pushed on-chain. Also, we can sto=
re more than 80 bytes for "free", because no such taproot branch will be ev=
er pushed on-chain and used as an input. That means we can use "OP_RETURN <=
1.5 GB of data>", create some address having that taproot branch, and later=
 prove to anyone that such "1.5 GB of data" is connected with our taproot a=
ddress.

Currently in Bitcoin Core we have "data" field in "createrawtransaction". S=
hould the implementation be changed to place that data in a TapScript inste=
ad of creating separate OP_RETURN output? What do you think?
