Historically, TV actors would push for (or even have negotiated) pay bumps 3/4 seasons in, as back in the syndication days, a show surviving that long would be in the black up to that point once those syndication deals were included.
So networks (or streamers) have every incentive to film ~15 to 20 episodes at once with the same cast and crew - a season contractually - but air that over two years as "two" seasons as far as the public is concerned, to delay when personnel get pay bumps.
Streamers specifically then have an additional incentive to split each of those 'seasons' into multiple chunks aired at different times to maximize the number of months people pay subscriptions for.

As far as Kurtzman, I haven't seen anything official, but considering the Warner Bros merger means Paramount have massive debt upcoming but also can't act as if the WB merger is happening until the paperwork is finalized, I don't think you're going to hear anything until his contact is over in August. I can't imagine he gets another deal considering how Section 31 and Academy have gone.
