Nobody was "hard on him". People simply said that the "bass" is not part of the "pro" equation. The "player" is. A Fodera doesn't make you a "pro player", just like a SX doesn't make you a "beginner or amateur player".
"For me" being the key words.
For the most part, correct. However, I did a major label album a couple years ago where I played an old Burns bass that had crappy fit and finish, didn't hold tune well, and was only "barely" set up - but it was the perfect tone for the song and the track ended up sounding great.
"Versatility" has nothing to do with a bass being "pro quality". In fact, I (and MANY other pro bassists) would much rather have a few "one trick pony" basses. Basses that do ONE thing remarkably well, instead of trying to be a "jack of all trades". Versatility, in
most cases, equals "lots of tones, but none of them
great tones".
I play 4 string basses. I make my living making music. I haven't "needed" a 5 string yet. I do occasionally tune the E string don to a drop D, or alternately, if I know the session will require a low B or such, I'll use a 4 string tuned BEAD with larger gauge strings. No big deal. 10 minutes for a string and nut switch.
My $.02 - and I'm sure that there are plenty of people that will disagree with my opinion.
