It's slow, but do you prefer "Move fast and break things"? Can you persuade bitcoin community to perform hard-fork even if there's tested solution which is ready to be deployed?
Well, I did find it interesting ...a few years past ...when the Bitcoin Developers said they had a plan for IF they ever had to emergency 'hard fork' again due to some
unforeseen problems with the Bitcoin Blockchain Network. In other words, not only would they do the fix for whatever emergency that needed a hard fork of Bitcoin to
resolve..they had some 'tweaks' and 'improvements' in place to add with the opportunity if a hard fork happening. I am 'unsure' if block size would have been in
this batch of options on an emergency Bitcoin hard fork..but would not be surprised if it was so.
But again, is there not just enough devs? or development $$$...because the bigger the project the more you need both. From what I understand the last ATH
bitcoin had 1 million users/adopters and now it has 100x that....so, something has to play catch up at the development end in either more people as devs
more money tossed at the problem..or both. Also to the 'price' of Bitcoin...leads to the 'status quo' bias:
