Add one more who has seen a couple tenths change in SQM-L readings at my dark site (21.9s now read 21.8s, sometimes 21.7s).
But as to whether I don’t observe DSOs due to this, heck no. I still observe.

This provides a very good extra argument to offer to your spouse to justify getting a bigger telescope! 18-inch Dob anyone? Just use all that aperture to bore thru those brighter skies! 
The early 'dark nebula' astronomer EE Barnard was probably the first to publish a paper about his so-called "night glows" and their impact on his wide-field astrophotography. ...and this was the late 19th Century! He brought up the subject often (one similar reference https://adsabs.harva...SidM....5..129B). I'm not sure what the astronomers of the time made of it - but almost certainly he was observing dim aurora or noctilucent clouds.
Somewhere on my HD I have copies of a few published papers of Barnard on the subject of "night glows" - but I can't find them right now. It might be a good topic to research on a "cloudy night". 
I also remember the topic being mentioned in typical amateur astronomy books of the 1950's and 60's -- back when Light Pollution was far less of an issue for most amateurs - but "night glows" were.
