It most likely will not work. As I have outlined in a recent post, there are too many different and "entrenched" camps.
There are a lot of different "camps":
1) BU only.
2) Core only.
3) Soft-fork only.
4) Hard-fork only.
5) Only block-size increase.
6) Only block-size decrease.
7) No hard-fork at any cost.
8.) Other?
We can even expand on this. There are people that think 51% of hashrate (node percentage is irrelevant) is adequate for a hard fork as an upgrade, and there are those who think that 100% is required. Both of these ideologies are absurd.
...
I agree with this and for some reason the community is blind to it.
There seems to be a denial and slight delusion about all this.
This is mainly why I have come to the unfortunate conclusion that a hardfork to
attack or to split the community is not far off now. We are just chasing the tail.
Also, I'm sure if the ETF is denied on Friday, Core supporters and BU supporters
will blame the other, and if accepted (which IMO is not likely) each side will take
the credit. The point being that those two sides are locked into perpetual hate.
