IMHO an approach that would not involve making a binary choice between
"full D" and "minimal D" is to add an option to make the linker strip
druntime and Phobos' shared libraries (or any shared library, and it's
not specific to D btw) to the "lowest common denominator" required by a
bunch of libraries and applications. Wouldn't that fulfill one of the
two goals -nodruntime is trying to achieve as far as I understand
(saving memory)?

And regarding the other goal, to help porting D to other platforms a
stub druntime would be cleaner than a hackish compiler flag that
requires many changes to DMD.

No. Any library compiled with -nogc will be 100% usable from a program compiled without it. Same goes for -noexceptions, etc.

This *is* a lowest common denominator. And as such, the lowest common denominator is fully usable from code outside the subset.

All these do is error on whatever feature they are disabling.
