I don't know about the insides of mysql, but surely it caches data of
common queries, no?  And far better than an intermediate backend could do
because the intermediate backend is not aware of possible writes to the
data by other sources (including in some cases itself.)

I remain curious on the strong goal here.  I mean yes, there can always
be value in extra levels of abstraction, but your talking raw SQL
and getting back only slightly modified query results so little abstraction
is being added.

Is it that sql query libraries are not available for some clients?  Is it
that they are too expensive?  Is it that they are too hard to code for?
