This thread is stretching out way too far without actually going anywhere. Looks like it's been 100 pages of going around in the same circle. Although there has yet to be presented a valid reason not to fork.
There is nowhere this thread could possibly go. The onus is on proponents of a fork to "present a valid reason." Also already covered:
XII. The current 1Mb limit is arbitrary. We want to change it. Please ignore the fact that the discussion is about whether to change or not to change, and please ignore that the onus is on whoever proposes change to justify it. Instead, buy into our pretense that the discussion is about "which arbitrary value". Because we're idiots, and so should be you!
Go away.
