As per subject, do you reckon Pace extruder groove cut outs actually extend the life of the chainring, or are they just a gimmick?

Yes, depending on type of substrate etc.
Only in my mind though, I have no proof!

In my experience the grooves don't do anything noticable other than make the rings harder to clean...

Pretty much impossible to prove without a lab set up.

Love the idea of them though.

I wonder if no one else has done it because pace patented it or because its a gimmick?

I reckon they work. I had some that lasted years in west Yorks mud. One may still be working on a friend's bike!
Problem was/is that if they work, customers don't come back for new ones for ages.

It's the same idea as grooved brake pads isn't it?

Might be due to the grade of aluminium used.
