Well, the second part of that question depends on the first part.
If it's just a way of getting better than sample accurate timing, I'm
not sure there is a reason not to use a hard-coded resolution. It's
definitely easier and faster. Fixed point values don't even have
problems with wrapping. Values based on arbitrary quanta do.

Yeah, but I'm worried about how plugin authors will ensure that their
plugins do the right thing. It's easy to get it "right" when you
divide and multiply by 1 all the time. :-)
