I don't even think Phi is intended to be anything other than an individual/hobby project. Has the author even commented here yet?

My point is it's not like they are intending Phi to replace sublime, they're probably just doing it for fun. Even if they are more serious, they're being honest about its short comings right now.

If you thought they were trying to determine which one to use, you misread the situation.

You can also compare apples to oranges.
