Long reorgs, only for old nodes, were a possibility, but not a problem.

The p2p network split issues WERE resolved well before activation.
(In fact, Bitcoin Knots still ships with the general p2p fixes.)

There was no measurable difference in community support between BIP148 and 
Segwit itself, months before BIP148's activation. (There was about 20% that 
indicated they would support BIP148 "only if Bitcoin Core releases it", which 
IMO "counts" in this context.)

The only difference was in the opinions of developers. Basing the decision to 
exclude BIP148 as even an *option* on this basis was IMO improper and 
shouldn't be repeated. The community's readiness to switch to another 
fork/build for UASFs is also valuable, but shouldn't be necessary.
