Not really.
They did a major revision in 2015, and based on the feedback from that pulled back from most of the changes to a much smaller revision. And based on the feedback from that, finishing the revision seemed to be a low priority.
After all, it's a month away from two years and nothing has been done, and only small tweaks were needed to balance the revised ranger. Feedback clearly showed they were either not on the right track or it was not a priority.
And it's not that the attitudes to the class shifted. It's that the negative attitudes were always a vocal minority to begin with and any changes likely ended up upset more people than they satisfied, paired with an influx of people who are just fine with the ranger how it is.
Yea, I think you've hit the nail on the head here. With these shifting demographics, who is served by the creation of a precedent of replacing published material for balance reasons?
New players don't care about what previous versions of the ranger did, are presumably less balance sensitive than more experienced gamers (as it's difficult to assess balance without play experience and having a fuller grasp of the system), and are more likely to look to the core rules as a guideline when balance questions do arise.
More experienced gamers in a house campaign can simply grab one of the myriad options of revised rangers already accessible, or make changes on their own to achieve the flavor and power level of ranger they want.
AL gamers can simply avoid the ranger if they think it's undertuned. For organized play, overtuned builds are more problematic than undertuned options. Undertuned means that one option becomes unviable, overtuned means that all options not also overtuned become unviable. (This is also for the AL gamer prioritizing effectiveness, which is not the entirety of AL gamers but somewhat more prevalent.)
The only real group of players affected by the lack of an official ranger are AL gamers that prioritize effectiveness but really really like rangers, and players in home games that like rangers, but don't like homebrew/houseruling. I personally believe both groups are small, the former need to simply suck it up, and the latter need to learn embrace homebrew, as WotC seems to be moving strongly away from prioritizing concepts being "official".
