On the contrary; it ABSOLUTELY is. Because not all Job Gauges are the same, not even REMOTELY. And unfortunately, even with the "grid-snap" function, not all of the windows line-up perfectly. Case in point; if you try to align any Class-gauge underneath the HP/MP bars, you'll notice they're off-center, by just a couple of pixels.
To me, that kind of stuff is infuriating. It can take several minuted just trying to get ONE BAR to have pixel-perfect alignment with another. But as is the case with the Reaper, sometimes different Jobs wind up having dramatically different "gauges", which COMPLETELY changes the way your layout has to look.
Again, I'm someone that values a clean-looking UI far more than the average person, but I still think it's a worthy cause. The default UI is just a mess. I mean, just take a look at this nonsense:

That is just... unacceptable.
