In my project, I migrated MyPackage into Pharo 7, and create
MyPackage-Pharo6 for compatibility.
Then updated BaselineOf to conditionally load MyPackage-Pharo6.
At some point, I will drop MyPackage-Pharo6 to make migration to Pharo 8
easier :-)

I haven't used branch or tag to support different platform versions.
I'd prefer branch over tag if I want to keep maintaining codes for older
platforms.
I'd like to hear how people are dealing with this issue, too.

Best Regards,
