Yep. The fact that PySqlite is now part of the standard library has
already created a de facto standard, and most other database modules
seem to follow it.

The "shortcut" methods you describe were explicitly removed when
moving from DB-API 1.0 to 2.0, so it's not a good idea to reintroduce
them :-)
But PySqlite has already reintrocuced them. They are now also part of
the standard library:
http://docs.python.org/2/library/sqlite3.html#using-shortcut-methods
Is there anything bad about these shortcut methods?
