This might work for subr-x and other elisp packages (in which case these
could just be added as dependencies to the effectively virtual package
compat).

On the other hand: If the functions are implemented in C, then they have
to be replicated some other way. And this doesn't just apply to
length{<,=,>}, string-distance, etc. but any function that might end up
using them down the call stack.

In principle, these two approaches can be merged, but I have the
impression that this would be more complicated
