To be honest, I'm scared of adding this kind of complexity to the
system. I appreciate the problem you're trying to solve but I worry
adding this kind of change is complex, invasive and introduces too much
risk.

I have some specific worries with this implementation too, in
particular that it changes on target pkg-config, it really should only
change nativesdk-pkgconfig? If we have risk, we want to minimise that
risk and adding this wrapper everywhere doesn't seem to do that...

Cheers,

Richard
