The idea of dbapi is to provide an API that is consistent regardless
of which driver you're using, so I'm not sure what you're driving at
when you say "seems fairly backend specific".  In what sense?

dbapi (deliberately) only specifies API conventions for a very basic
subset of operations, but unless you're looking to do something fancy,
that shouldn't be a hindrance [1].


[1] If you're doing anything non-trivial with databases you will need
to write different SQL for the different backends anyway because each
DBMS will have a different feature set, different interpretation of
the SQL standard, different ways of optimising queries ...
