Maintenance is nothing new.  It has been around since day 1.  Today we
have a choice, so if you are that worried about maintenance use HR.
Consistency can be dealt with by using ancestor queries.  Also,
remember a .get() will have Strong Consistency, only queries must have
ancestors to have strong consistency.  Also, in my experience almost
every query has strong consistency within a few hundred
milliseconds... So for me it was a no-brainer.  I guess high usage
apps may be bothered by the pricing, however I can see no other reason
to not switch to HR asap.

my 2 cents
