Andrey Stepachev commented on HBASE-13087:
------------------------------------------
Because it can have no code for coprocessors for example.
So when we add new coprocessors we should be sure, that
those coprocessors have recent code. That is why it much better
to have strict policy on which RS can run system tables.
(actually that is wider problem, any system coprocessors
need to be consistent with expected structure of system table).
