Considering that for most banners the "consent" is the easy option I assume a lot. People want to get rid of the banners.
However I claim the point of the bad UX is to make users angry and then have them complain about EU etc. "demanding" those. In order to weaken the regulation of tracking. If they are successful (and they are making progress) "no more cookie banners" is a lot better headlines than "more tracking"
Those are technically in violation of the GDPR since the opt out is required to be just as easy as the opt in.
The failure of the EU was to not write into (an updated version of the law) that setting a specific HTTP header means "no", and "no" means "no" not "show me a popup to ask" (i.e. showing a popup in such cases would not be allowed).
