WWE hasn't cared about the tag division in years. I can't remember the last time they actually cared about it. I remember in the 80's/90's it seemed like there was always 10-20 teams and there were teams that seemed deserving to hold the belts that didn't.
Yeah, this is hyperbole at best. During the 80s & 90s, there were still only ever a small handful of tag teams that were money. During the 80s, you had the British Bulldogs, the Hart Foundation & Demolition as the only genuinely strong tag teams in WWF that made a splash in the company. Just about anyone else were used as jobber tag or the titles were put on guys like Rick Martel & Tito Santana, who weren't really priorities.
During the first half of the 90s, you had the Legion of Doom & the Steiner Brothers. The second half of the 90s, the only really great tag team in the company was the New Age Outlaws. Guys like Edge & Christian, The Hardy Boys & The Dudley Boyz would rise to prominence beginning in the early 2000s, but this was when WWE started playing hot potato with every title they had, a common theme for both WWE and WCW during the Attitude Era.
In-between the good teams, you had loads of lame tag teams like Greg Valentine & Brutus Beefcake, Mike Rotunda & Barry Windham, Nikolai Volkoff & The Iron Sheik, The Colossal Connection, The Natural Disasters, The Quebecers, Men On A Mission, The Smokin' Gunns, The Bodydonnas, The Godwins, The Headbangers, The Big Boss Man & Ken Shamrock, Too Cool and loads of other tag teams.
I've never really seen a tag team division in any company with 10 to 20 great tag teams. While it's certainly true that the WWE's tag team scene, for the most part, hasn't been much to speak of for a long time, with an exception being from about September 2012 to about September 2014, it's never been this paragon of greatness. I know people like to look at the "good ol' days" through rose colored glasses, but I've been watching WWE since I was probably 5 years old and I don't remember a roster jam packed with championship caliber teams.
