Goku & Frieza are in an interesting place in their rivalry. Not the enemies they once were, not allies, just somewhere in between. Moving forward, it can go either way.
In my opinion, I think Frieza will serve as the being that will keep any other evil being in universe 7 in check. There will be no other adversary to threaten the peace since him & Goku have a "truce." That will open up the opportunity for Goku & friends to help the other universes with their problems (goku kinda confirmed it too. Despite Freezer rebuilding his army, Gokou basically said if he fux up 1 last time he'll just get beat up again & sent back to hell, & Freezer knows this). That's my theory.
