oops, forgot about that whatchmacallit link mention. Perfect setup. Without taking a peek at a gearing chart, I suspect your "stupid low" is very similar to my "stupid low" on one of my bikes, which uses 26in wheels, a 44/32/22 and 11-34.
Bottom line--there is no downside to really low gearing. None whatsoever. The times you use it, and Ive used my 16.7 gear inch low gear lots and lots and lots of times, whether in Latin America or France, and I have enough touring experience now to know that it doesnt reduce my manhood or anything like that, in fact, it saves my and anyones legs for those times its nice to have. When you dont need it, you shift up, simple as that, and it doesnt make you slower like some people think, it means you can save your legs and be fresher over teh day with less muscle and knee fatigue.

I'll finish my blah blah with the question of do you use and have a mirror? Super important doohickey in my humble opinion. Very simply, it can give you a few seconds heads up of potential serious situations, knowing when to pull over to the side or whatever, and also simply to be more relaxed because you know more of whats going on behind you with just a glance. Ive used a helmet mounted one for many years now, and dont care how dorky it looks. Wouldnt ride without it.
