Dunno if it's actually true, but I've found some coatings do better with no maintenance than others. Take for example the following fleet vehicle:
Van 11: XXX + XXX applied March 2017; refresh 01/2017 decon wash, w/ XXX clay, XXX & XXX
Since 01/2017, about 45k miles ago this vehicle has received no bucket washes and has *maybe* run thru a touchless soap/rinse tunnel wash once or twice. Pulled the vehicle outta hibernation last week after sitting outside idle since 11/2018 and it's still looking very, very good as far as gloss and cleanliness go. This coating has exceptional self-cleaning abilities and, to throw another apparently contentious point into the mix, is and never has been a great 'bead-er' but more of a 'sheeter', hence my preference for sheeting as opposed to fantastically formed beads.
Now as to the specific coating that's the topic of the thread, if ya wanna know how CQ UK 3 + Gliss V2 does with absolutely no maintenance, check back in a year cuz the vehicle I just used it on will likely see a touchless tunnel wash or 2 in the next 12 months...if it's lucky. Otherwise I'm depending on Mother Nature to occasionally give it a good rinsing.
As always, just my opinion from what my eyes have seen and YMMV; not a pro and it is well within the realm of possibility that I have no idea what I'm doing or talking about....and yet the Van noted above pretty much always looks freshly washed, barring extreme incidents. It is what it is....and to be perfectly honest I don't really care about the what's or why's it does what it does, just happy it does it.
