I have no particular interest in either a Seven spin-off series OR the Section 31 spin-off series.
There’s a lot of real lessons from the end of the Berman-era about market saturation, dividing the efforts of the creative staff, and generally just trying to do too much at the same time, to the overall detriment of all the projects.
It does sound like Chabon wasn’t being particularly serious with this suggestion anyway but, even if he was (or maybe if he was just sounding out what responses it got), I still think they need to stop, pause, reflect and not over-stretch themselves.
There are several other projects in development and it sounds like a good possibility that the Captain Pike / Spock / Number One series set on pre-TOS 1701 will also move forward. That one I would definitely watch and it gives them at least one avenue for a 2020s take on classic episodic Trek.
In truth, Covid-19 is likely to close down most active productions for the foreseeable future. Shows in post-production can, presumably, be finished remotely if needed; an animated show the same; but anything requiring new live-action shooting (even pick-ups and re-shoots) seems unlikely to be happening for quite some time!
