How hard would option 2 be, removing those using-directives?

If you want to repro the problem, you can build this little demo benchmark: https://github.com/tkoeppe/tarpit/blob/bab67d3bbe7b077cebee06d05591a37ed977516b/sandbox/BUILD#L41-L46 Just adjust the repo's Bazel WORKSPACE to pin the benchmark revision to the broken one.

@dzarukin That sounds great, thank you very much!

Hello :-) Did you happen to get a chance to look at this?

Sure thing, thanks!

If we build wheels with macos-11, will that make the wheels less compatible? Or are we expecting most users to be recent enough?
