As far as I am aware of, there is currently no ability to filter the deletion log by deleted revisions, which is getting annoying especially if one tries to follow a user's activity in this area on a wiki where the average of deleted pages/day is pretty high (like for example on Wikidata).
For deleted pages, there is additionally also the ability to browse them (through Special:Undelete), a feature which lacks completely for revdel.
Thus, I would find it reasonable to either split the logs (into for example a "Revision Delete Log" or merge it into the OS log without making the non-public part visible to non-oversighters) or to add a filter to the deletion log.
