I agree with you, my Birdy has a compact crankset 52-36 and a 9-32 cassette and indeed, I almost never need the 36t chainring. I could as well remove this chainring + the front derailleur system and save weight.

I have minit lite PT tires in ETRTO 406 on another bike and they are good tires. The problem is to find them in ETRTO 355 for the Birdy, they seem only available in Japan and Singapore ?
