"most call sites" would be fine. The common use case matters, it's not that
hard to conditionally call a different function, as long as that's the
uncommon use-case.

The other key here is that even if a boolean flag does essentially select
between two different function, there are times where there is more than
one such boolean flag for a single function, so you end up with 2**n
"different" functions -- in this case, probably better to just use the
flags and have one calling point.
