Progress should be layered, not bloated.
I agree to this. We already had the mess with inscriptions and what not on taproot. I fear that this will make that spam return.
On the other hand, cleaner code and more lively mempool to keep the miners happy is also a possible point, plus... maybe, just maybe, people got bored of inscriptions and similar crap.
I find it unbelievable that this happens after so many years of block size debate. Somehow I fear we are going on the wrong direction (for some while already).
Back to current change: technically there are pluses and minuses, many of of them not technical and hard to assess their long term impact.
