Hi all - Sorry if this is a long-resolved design decision, but is there a good reason that MakePoint accepts double precision inputs while MakePointM only accepts single-precision floats?

In my use cases single-precision resolution is not fine enough, such that MakePointM can't be used. My tables will accordingly need a double-precision POINT geometry object and then a separate column for the m-value.

Thanks,
Andy
