Isn't the issue here that there are two forms of compatibility being
talked about? 'Script language' and 'library API'.

For comparison, C and C++ compilers don't tend to talk about the
language spec in their version numbers.

On the other hand, the Lua method of <lang>.<api>.<bugfix> makes sense,
if you're aware of it (you're unlikely to see the language change
without also changing the API). But I can see package maintainers being
confused.
