I dont know ow experienced you are, but tools are their to rapidly see the history of objects, to confirm or not that prior to last edits these objects were valid,
If for example there is a valid relation, either to describe a territory, a river, a route network, if an inexperience contributor deletes some or all the members, it is important to repair, and not simply blindly update and destroy, creating even more problems.
We surely should not encourage contributors to simply fly over a territory and garden, blindly pick this, remove that thinking this is not usefull.

I would be scared to do what you are suggesting. We can't know what the original intention of the previous user were. This could create duplicate objects or reintroduce data that were meant to be deleted. In the end more mess then it's worth.

It is not clear if you only want to delete relations that never had members. We need to be carefull about mechanical edits if a prior contributor deleted the members.
You need a tool to look at the previous state of relations and try to repair it. History tools might help. See for example https://osmlab.github.io/osm-deep-history/

I had an idea that came during my work on a buildings import. I would like to clear/fix improperly created/deconstructed relations. This would include:
1) Remove relations that have no members, nor are members of a relation themselves.
relation[type](if: count_members() == 0);
rel(br) -> .parents;
(._; - rel(r.parents););
2) Remove type=multipolygon from ways.
