Interesting, you would think they would have got her signed up in preparation for it to make sure she is available.
Is CBS considering making changes to their plans, there has been a lot of interest in a Pike show but very little for the S31 show, I am fine with both of course.
Kurtzman stated Michelle Yeoh approach him about doing more (which lead to the idea for the 'Section 31' series; but they're not going to hammer out any contractual details until they have the particulars ironed out and a tentative shooting schedule, etc. Patrick Stewart is going to be 80 in 2020, so it makes sense that if he says 'yes' to a series, they are going to really fast track it - which they did.
Star Trek Discovery's development for first announced in November 2015. 'Section 31' was announced as 'being developed' in January 2019 There's been stories that the details and story line are being developed:

It’s worth noting that the way Stapf is talking makes it sound like the Section 31 show is set to go, however, CBS has yet to officially confirm a full series order. When it was
officially announced in January, CBS only stated the show was in development, something
confirmed later at the TCA event, but it was also confirmed at the same event that showrunners
Bo Yeoh Kim and Erika Lippoldt were at already at work and “breaking the story.”

But yeah, they're currently in production with two live action series (Star Trek: Picard was sooting the last 3 of Season 1 and Star Trek Discovery just started filming Season 3), so yeah, that 'Section 31' is still in development and hasn't gotten an order yet isn't all that surprising with all they have on their plate. The series order could be weeks away, a couple months away, or yeah, they could decide not to go with it; but again, I think CBS would be very happy to get Michelle Yeoh to headline a Star Trek series that has the potential to bring in new fans worldwide who might not give Trek a look, but time will tell.
And yeah, as to the comment:
"there has been a lot of interest in a Pike show but very little for the S31..."
^^^
Please. There was nothing but virtol from a majority of Trek fandom as soon as more concrete details leaked about 'Star trek: Discovery' - and hell unfounded rumors "Discovery's SO BAD CBSAA will never air it, and is scrambling for a replacement...", etc.
Heck, from the comments of a few on the BBS (not the person I'm replying too, this is a general comment from me); who can't believe 'Star trek: Discovery' was able to bring any new fans (for whom this is the first Star Trek series they've seen, or become interested in) -- but it has, as ALL NEW incarnations of Star trek have.
In the end, I don't think the fact that there's no episode order at this point means CBS is considering dumping plans for the Section 31 series. With two Live action series in active production concurrently, three already order animated series in concurrent production, and six 'Short Treks' in post production; I'd say they're very busy right now, and the 'Section 31' series development is continuing <--- Or at least we've heard no claim to the contrary from TPTB.
