Ok yes with Oculus it's similar actually. You can poke at the letters but the problem is the exact depth detection is not so great (mainly because you're pointing directly away from the tracking cams with your finger) so it's a bit of a hit and miss.

And moving the "virtual mouse pointer" and then pinching is also a pain to do. My oculus doesn't have eye tracking but you can move your hand to move the "pointer".

Both methods are a PITA. Using the controllers to point and then click the trigger is better but it's still slow going of course that way. It's like typing on a keyboard hanging in front of you by pressing the keys with a stick. Considering that's the most comfortable option (which the Vision Pro doesn't have for lack of controllers), it's pretty sad.

But yeah I see the potential too.. I hope it will come to pass.
