I don't think alternatives should be used for versioning. For example,
we don't use alternatives for gcc, neither for Python. We would start
getting errors about "package X does not compile on my system" or
"module Y does cannot be compiled".
In the bug report, I just see that some upstreams didn't account for
multiple versions installed. But since it is something that exists for a
long time to choose the C compiler (and some other tools), I think they
will eventually adapt.
