[~vrodionov], you still feel like doing this? NP at all if not, I'll make a patch in that

> Currently, if store has one (major compacted) file, the only case when major compaction
will be triggered for this file again - when locality is below threshold, defined by *hbase.hstore.min.locality.to.skip.major.compact*
or TTL expired some cells. If file has locality greater than this threshold it will never
be major compacted until Store's TTL kicks in. For CF with KEEP_DELETED_CELLS on, compaction
must be enabled always (even for single file), regardless of locality, when deleted cells
are expired (*hbase.hstore.time.to.purge.deletes*)
