If I understand this point correctly, you are concerned about
"FloatToStr(Now)" statement, where compiler is explicitly treating
TDateTime as a floating point value.

This creates a problem *only* if base type of TDateTime is changed to
something other than a floating point value, a record for example. Is it
foreseeable that TDateTime will change its base type? In such case I
presume there would be some serious breakage in RTL.

2. Some targets do not even have floats.

This feature can be IFDEF'ed.

P.S. I'm intrigued and curious about such subtleties. Forgive my ignorance
if this makes no sense.
