Basically, the law created enough fear among the lawyers that software developers are being advised to include the cookie banner in cases where it isn't strictly needed.
You'd have much better retention rates if you don't cover up the content the viewer is trying to view.
How would you like it if I shoved a banner in your face the moment you walked into a store and forced you to punch a hole in it in order to view items on the shelves?
So uh, don't do that.
You don't need to notify if you use cookies for required functionality like login sessions or remembering a functional setting.
If you're tracking whether they're returning or not your activity is exactly the kind of behaviour the rule is covering because, in legal terms, it's skeezy as fuck.
Nobody wants to be the EU test case on precisely how "required functionality" is defined. Regardless of what the plaintext of the law says, it should be self-evident that companies will be more conservative than that, especially when the cost is as low as adding one cooke banner and tracking one preference.

Go to that link, these are the cookies it writes (at least for me):
* _ga
* _gcl_au
* octo
* ai_session
* cfz_adobe
* cfz_google-analytics_v4
* GHCC
* kndctr_
*_AdobeOrg_identity
* MicrosoftApplicationsTelemtryDeviceId
* OptanonConsent
* zaraz-consent
Some are from github.blog, some are from the cloudflare.com hosting. Not sure how the laws apply to that. But obviously there's several analytics cookies.I think in the past you still needed some info box in the corner with a link to the data policy. But I think that isn't needed anymore (to be clear not a consent dialog, a informational only thing). Also you can without additional consent store a same site/domain cookie remembering you dismissing or clicking on it and not showing it again (btw. same for opting out of being tracked).
But there are some old pre-GDPR laws in some countries (not EU wide AFIK) which do require actual cookie banners (in difference to GDPR consent dialogs or informational things). EU want them removed, but politic moves slow AF so not sure what the sate of this is.
So yes without checking if all the older misguided laws have been dismissed, you probably should have a small banner at the bottom telling people "we don't track you but for ... reasons .. [link] [ok]" even if you don't track people :(. But also if they haven't gotten dismissed they should be dismissed very soon.
Still such a banner is non obnoxious, little annoying (on PC, Tablet, a bit more annoying on Phone). And isn't that harass people to allow you to spy on them nonsense we have everywhere.
