Actually, I'm asking for something exactly like the arch
option for MSVC/-mfmath
option for GCC/etc, and have it respect that for CTFE.
MSVC doesn't appear to have a switch that does what you ask for:

Apologies if this has been addressed in the thread, it's a
difficult structure to follow for technical discussion. You seem
positive about software implementations of float. What are your
thoughts on having the compile time implementation of a given
type mirror the behaviour of the runtime version?
Fundamentally whatever rules are chosen it would seem better to
have fewer rules for people to remember.
