Answering for this particular case only, I'd say yes, it's safe. No problems were encountered, and there's no reason to expect that any will. It's an uncontroversial feature whose promotion out of experimental status was unanimous. It will only officially come out of experimental when 5.24 comes out next May-ish, but it's safe bet it will.
