Would it make more sense to keep the original configuration and add a new one, as Arm and AArch64 have done?

The new configuration would use the same cache file and just override the 2/3 things needed. I assume - but don't know, that you'd want to check exceptions on and exceptions off. Throw rtti into the exceptions config just to keep it simple.

Armv7-M picolibc -fno-exceptions (which is the current one but renamed)
Armv7-M picolibc (implicitly exceptions and rtti)
