Scan implies scanning table and this is what I would like to avoid. I consider "bulk" delete
as a hint (internal filter)
for HBase (RegionServer) execution of which can be deferred  until actual region compaction
kicks off.

Why does some one need this for? CF TTL is not enough in some cases and there is need to have
more flexible API to perform
HBase housekeeping.

This is interesting.

Worth considering a Delete API that takes a Scan (or equivalent*) as argument?

* - Possibly pulling up the start row, stop row, filter chain fields
of Scan into a more generic object that can be passed to such an API
and extended by Scan, if the use of Scan in an API like Delete leads
in consensus opinion to a mixed metaphor.
