Yes, libgcc_s is carefully built with carefully controlled exports. They are controlled by:

when someone wants to export one of the symbols, they can just add it to the list.

OK, my question was phrased poorly;
I understand the mechanism - what I don't understand is the rationale.

What is the benefit of splitting the publicly exported symbols between libgcc_s.1.dylib and libgcc.a?

This forces us to -lgcc, even in a hypothetical newly-released case, where the libgcc_s.1.dylib is completely up-to-date.
