Yep agreed Quito is very compromised, yep has many mistakes. However, I've yet to find better in some contexts. It is more of a walking than a cycling cut due to the excessively shortness at the rear, it is about 6" too short for cycling. However, if you're wearing waterproof pants then the short cut is not really that much of a problem.
Paramo's waterproofness is not a function of zips, you'd be allowing water in via zips and aiming to be warm for baselayer to evaporate and the Quito liner to let that pass through, it might condense on the inside face of the outer layer but the inner layer won't let it pass back in, and then let body heat keep the moisture going in a generally outward direction.
I biked today for an hour doing grocery shopping in the Quito in constant rain, I was dry.
Compromised, yes, example of dumb designers, yes, ignoring customer feedback, yes, but it still can defeat the wet stuff if you know how the fabric works, and do it better than many alternatives. The key positive points are the fabric, the hood, sleeves and the pitzips.
