Some comments on the arguments:

(1) SQLite did never claim to be as "complete" as other databases -- it is and will be a "lightweight" database.

(2) Everybody with marginal knowledge of different databases should know, that using different databases always puts you on risk and needs extra testing. You would also not recommend to develop your application on Linux, use a crosscompiler and ship the product on Windows untested. And with that said, most of the arguments can be deleted.

(3) When you are using an ORM, most of the arguments are obsolete, too.
