This is not true.  Until now, -ms only supports integer values.  With
the new method, fractional point sizes, starting with 3pt up to the
limit of (2^31-1)/100, are supported.  Below 300pt everything will
stay identical to the current behaviour!

There is no limitation at all.

Been there already.  As you correctly say, your solution is

I can only repeat that my solution isn't `incompatible' -- a point
size of 10500 is really unrealistic, so I'm basically only using point
size ranges which make no sense otherwise.

Answered elsewhere -- floats are used in groff, but not for registers.
