Well, yes, but that's exactly what I mean. I take the GPWS as something that will warn me that my situational awareness is not as good as I thought. Once I doubt my SA I have to go away from terrain.
By the way, TOO LOW FLAPS is a go around, according to the procedure. You are really low if you hear that and you still don't have the flaps…
The TOO LOW TERRAIN is what you get when you are not so low yet, but you are very low indeed. If you are too low you did something wrong, like busting a minimum altitude or something. Go away, I say. I guess there are scenarios where a TOO LOW TERRAIN or a TERRAIN TERRAIN do not require a go around or climb initiation, specially when in VMC daylight, but I bet most of the times the best course of action is go around or climb.
