Why is Daml-LF 1.14 pacakge called 1_13?

When I look here:

I can see that the protobuf package name for Daml-LF 14 is actually daml_lf_1_13. (Note the mismatch with the java_package option below). Is this deliberate? Is there some interesting reason for this?

Good catch. The PR #15550 fixes the issue.
