accept all TLS certs for localhost

I am not familiar with the context, but in terms of code LGTM

The idea is to allow localhost connections regardless of the certificate used, because the cert is usually only valid for the external domain.

Do you wanna add a map of localhost, 127.0.0.1, ::1 just in case? Would that be a better idea? Is there a way we can cover more variations of localhost?

shipit. localhost should be good enough. In fact after a quick check there are even places in net/http code where they just check localhost.
