I don't know how the MacOS toolchain is designed.

But in general, the toolchain must be configured with the *oldest* supported OS 
version to provide binary compatiblity. At least, that is how it works on 
Windows (through _WIN32_WINNT) and on all ELF-based platforms (through custom 
build roots).

Well, hmm, your "problems" very strongly suggest that you failed to deactivate 
those "features". I think you answered your own question.

This adds about 80kiB of dead binary (stripped) code *per* plugin on Windows 
or 1kiB on GNU/Linux. You do the maths with over 300 plugins.
