Not at all. It's been six years. According to the people who own the game, it received and continues to receive a huge influx of new players, probably the biggest influx in its history. 5e was forged on the feedback of people who played D&D before it but it's pretty reasonable to say that, between new and returning players, they are not the majority of the people providing feedback anymore.
That said if you want to believe that a class that:
- Uses a different casting pattern, to the point that even its signature cantrip is different from the other damage cantrips;
- Runs its own independent and concomitant "feat system" (that would be the warlock invocations);
- Kind of picks two subclasses instead of one...
... would pass the current surveys. I find your faith comforting!
