You don't need to get the main chamber to 0 to adjust the IRT on a Mezzer pro, as long as IRT pressure > main pressure (which is always) the floating piston stays fully extended. Can't understand why it would be any different on the EXT fork, it's the same tech but I'll take your word for it. Regardless, deflating and re-inflating 2 chambers is still less than 10% of the amount of dicking around it takes to add/remove a spacer, and at least you can fine tune things as opposed to making big jumps between settings... Let's say a volume spacer is equivalent to 10 psi in the IRT, what do you do if you need 5 psi? Add HSC? Then your fork feel like shit in small chatter? Yeah, no. If damping has to rescue your air spring because it isn't tunable enough, you fork isn't working all that well.
I change IRT pressure a whole lot depending on what I ride. If I had to remove tokens after a day in the steeps because I'm doing jumps the next, I'd have worn through a couple cassette tools by now. I guess you can be happy with X numbers of spacers in place and the fork working OK for everything, but what if you could be happier with 15 seconds of pumping and the fork working better ALL THE TIME ON EVERYTHING? No brainer in my book.
For the EXT air shock, different issue, need to see how well the dual chamber system works. Much smaller air volumes, much higher pressures, leverage ratios >1, apples and oranges. But if it works at all it will suck a lot less than a token-based system.
