Good question.  I asked on #machomebrew about how they build the binary 
packages, whether a package intended for a certain macOS version is 
always built on that version of macOS, or there is some cross-version 
compiling involved.

Until we have proof that it's necessary, I think what you have done is 
fine.

Makes sense.
