Should all mourning-aveilus questions be cotagged minhag-tradition-custom since the legal status of the vast majority of its rules is custom and not halacha? Is there a specific set of mourning questions that should rather bear halacha-jewish-law for technical reasons?
Generally the set of rules is referred to as nihugei aveilus rather than hilchos aveilus for this reason.
As I mentioned elsewhere, I don't think the halacha-jewish-law tag should apply to all halacha questions: only to those that don't have a halacha tag of narrower scope. The same for the minhag-tradition-custom tag: IMO it should apply not to all minhag questions but rather only to those that don't have a minhag tag of narrower scope. I think (though I'm willing to be convinced otherwise) mourning-aveilus is such a minhag tag of narrower scope.
