Why concern with database abstraction?

I looked at the docs on the website and I don't understand, why are you concerning yourself with database abstractions?

V already offers an orm, a user could just use the orm in the route handler.
I do not use any orm, I can just call whatever I want in the route handler.
So why is mantis providing some database abstraction, which only supports sqlite, and still requires users to type raw sql?

I think maybe you could just not worry about that, and instead focus on other aspects of a web framework.

I really don't like veb and I am considering switching in the future. I found this part of the docs confusing, because it suggested that no other database is supported, which can't possibly be the case 🤔
