Even if we consider saving around 200gm (FD, clamp, bolts, chainring, cable) for a purpose-built "specific conditions" bike significant or important-- which I don't, especially for tri-- how many people are doing it for that reason? Hell, the OP doesn't even know if he needs the big ring or the small ring...
If you really don't need the extra gears, you don't need 'em; I get that, and I must confess that, as a guy with 8 bikes, I own a couple of 1x drivetrain bikes, but they're not what I'd consider "road bikes" even though they do get ridden on the road. But maybe that's my problem: I just can't imagine how other people ride. I should shut-up, I guess.
