This is just standard operating procedure for CBS/Paramount, who have viewed Star Trek as a big enough draw to attract audiences to new distribution channels for decades.
Back in the '70s they planned to use a Star Trek: Phase II series to launch a new network that never got off the ground (see https://en.wikipedia.org/wiki/Star_Trek:_Phase_II).
Then in the '80s they used Star Trek: The Next Generation as the flagship for a new, syndication-only system of network-unaffiliated TV stations.
Then in the '90s they revived the dream of a Paramount network in the form of UPN (see https://en.wikipedia.org/wiki/UPN), and created Star Trek: Voyager to attract viewers to that.
These efforts have had varying degrees of success, but they've never failed hard enough to shake CBS/Paramount from the conviction that new Star Trek is something people will want to see so badly that they'll be willing to change their viewing habits to get it.
Berman and Piller were a much better team.
Maybe worse, actually.
The "Captain Worf" show was AFAIK never in serious consideration. Michael Dorn was a huge fan of the idea and kept proposing it everywhere he went, which is the only reason it gained as much publicity as it did, but as far as I can tell it was never taken very seriously in the studios.
And I'm kind of glad for it - Worf is great, and Michael Dorn seems like a great guy, but Trek has always been about the ensemble crew and not revolved around any singular character. "Worf feat. crew" would've been a huge thematic departure.
In any case, I'm pretty sure this will be in the alternate universe (JJ Abrams-verse). It just doesn't make sense to have something in the Prime universe anymore, commercially at least. This makes me sad. The fact that Kurtzman is involved IMO suggests this is definitely a reboot-universe thing, as does the rumor that Bryan Singer might be producing.
That said, Brannon Braga and Rick Berman not being involved might be a good thing...
