Approving as a serious issue without a workaround. Only Go 1.16 needs this backport.

d515b24 
…path elements

These were always disallowed, but the restriction wasn't enforced in
most cases until Go 1.16. That's broken more projects than we hoped.

This change allows leading dots in import path elements. Leading dots
are still not allowed in module path elements. Leading dots were
always allowed in file path elements. Trailing dots are still
forbidden in all cases.

For golang/go#44647

This incorporates CL 298009, which allows leading dots in import path
elements but not module path elements. Also added a test.
