I am aware of that PR, as of yet that is not in the build and is a theoretical fix to that on a deniability basis. Again though, bitcoin is a monetary network and the claim that the thing hindering a robust layer 2 is the size of the OP_RETURN field, is dubious at best. By my estimation therea not a single need for the datacarrier size to be over 100 bytea even in the most complex layer 2s I've seen. Now minting a shitcoin on bitcoin however takes much more data. I am less concerned with the "Think of the children" wrapping paper than the "Limiting arbitrary data is authoritarian" wrap. It is smuggling so many intended consequences I haven't even thought of the unintended ones.
