I'm familiar with this but either ways the facts are not siding with the idea of an emergency. Most ordinal projects are dead, investors are ruined, and tx fees have been ridiculously low for months.
Besides, you are conflating two very different issues, just like BIP110 is doing. Capping OP_RETURN, which has outlived its utility, to protect nodes from hosting contiguous illegal content is arguably very important. Dealing with witness-embedded spam is secondary and optional. Witnesses can be pruned away, and it's not even sure jpegs are coming back. The were economically viable just because of a hype that is long gone and, would it come back, unsustainable by nature.
As I said, by trying to achieve aggressively everything at once, this BIP is not only harmful to legitimate monetary projects lead by genuine bitcoiners, it's also condemning itself to fail, missing an historic opportunity to fix a long-standing vulnerability.
