In general is it a good idea to use iota with floating point

I guess you're thinking of the difficulty of making exact
equality comparisons between the current value and the end
value? A floating-point iota certainly allows you to represent
certain things quite elegantly, although I suppose for safety's
sake you might want to use an integer-based iota and calculate
FP values from that.
In any case, the usefulness of closed-vs-open boundary
conditions isn't limited to FP iota, although it's certainly
the main use case.
The only time I could possibly see a use for open-close in iota,
is when you want to iterate all the way to T.max.
But I don't think that use-case justifies the change.
