There are no hard rules on what goes where but there is a general convention that Depends is for vital things, Recommends is for "standard" user-level things, and Suggests are totally optional.

It's nice if it *does* work, but mostly just for testing users' own
modules written to work with Sage.  As long as they can install some
additional recommended packages easily, I think it's fine.  Most users
of Sage just as a CAS (and not doing development) won't need `sage -t`
to work out-of-the-box.
