Getting passed all the implications for LN & multisig congruent addreses, of which im not fully clear on,
Hardforks are a risky endeavor.
Discussion
Block size reductions can be a soft fork. And 1MB is still ample size. Yes flood and loot attscks might become marginally easier but if LN can't solve that at 1MB, idt it can solve it at ~2.2MB (realistically, LN Txs can't make a 4MB block)
You really think if that were to take place that people wouldnt attempt a hardfork?
Also, dont you think 1mb blocks could end up sending fees back to a point where congestion for block space could be a real issue?
btc had some crazy mempool backups back then if my memory serves me well.
