I like 3/8 10 pins. Prejudice against 11tpi because then people will accuse me of coveting southwest. 18tpi is the standard for ferules if you ever happen to use a pre made one. Other than that I agree completely. I use 16tpi anywhere I can because on my metal lathe you can engage it on any number or half number on the thread dial without risking cross threading when using multiple passes. This is quicker for me than waiting for the dial to come around to the right number and also eliminates boo boos when my mind is wandering.
Who uses "standard" cue building threads?
Mostly the repairs guys because it's easier for them.
All of my threads are my standard and very little of any are standard cue building threads.

I do very little repairs on any other cues so it really doesn't matter to me.
