Agreed, That's certainly what I do and how I use it, also BS4 is very modular, you can tear out all the bits you don't use (or comment them out in case you ever do need them) and it's relatively trivial to alter other things (I use a 24-col grid with a 16px gutter width instead of the default 12/30 etc).
I could replicate the bits I use from bootstrap using something else or from scratch but the RoI in terms of time invested just makes no sense.
I don't think I've ever used bootstrap 'as is' since 2, I generally create something similar to a 'theme' that is layered on top of whatever is BS-current, makes upgrading a lot less painful that way since I isolate a lot of my changes.
The big advantage is done right you leverage all the thousands of bug reports to fix things without overly constraining yourself.
