IME the only thing -march=native does is it makes it impossible to boot your system on an older microarchitecture (which is trivial with Linux otherwise — I really don't understand those who bring their bad Windows habits and do a reinstall when moving between systems).

I mean, it would do that. But, I also have never just moved the hard drive between machines. I've only owned two machines in the last decade. So, not even something I have had a lot of opportunity to do.
Back to the point, though, I'm assuming that libc dynamically does most of the optimizations that native enables?
