The name "frange" does not necessarily imply that we have to mimic the

as expected while addressing floating point subtleties through
optional arguments and documentation, I don't see why it can't be
called frange() *and* support count.
But I do. :-) Calling it frange() is pretty much *begging* people to
assume that the 3rd parameter has the same meaning as for range().
Now, there are a few cases where that doesn't matter, e.g. frange(0,
100, 10) will do the expected thing under both interpretations, but
frange(0, 100, 5) will not.
What about the idea of this signature?
frange([start], stop, step=None, count=None)
Then when count is desired, it can be specified, and when step is
sufficient, no change is necessary.
