The real alternatives to löve are not Unity, Unreal or Godot, but maybe raylib or other much smaller libraries (not engines). löve is much different than Godot and good for entirely different projects and different people. The people that would probably end up löving löve in the long run would not be too interested in using Godot at all (such as me and many other löve users that I know).

I don't use it much at all anymore (though I have heavily in the past), but I would still recommend it to everyone for which it would be a great fit. If you just want to have a game running asap, then yes, maybe Godot is a better fit, but it's not categorically.
