Aren't real bugfixes (that actually changes present behaviour) separated
from style changes?

Don't get what you meant with 'unintentional occurences': if it is not a
bug and not a code style violation, than it it does not look as
something that should be fixed. But if there is an example, where
luacheck reveals a place that is worth to change for, say, readability,
then okay.

I bet a beer that this certain warning does not give us any real bug.

The main advantage of luacheck is preventing some kinds of typos: say, a
typo in a function name in some failure branch, which is not covered by
tests. The tool is definitely useful without the redefinition warning.
