SQLite limitations still in effect?

[brandonzylstra]

Supported databases are PostgreSQL and MySQL. Note: Unfortunately, SQLite raises a poor error message by which we can not determine exact foreign key which raised an error.

SQLite has gotten a lot of attention in the last years and the whole ecosystem has improved a lot. I would not be surprised if SQLite itself has improved their error messages. Is it possible to lift this limitation?

Or has this gem been abandoned?
