Like the star trackers. We can't even open the doors right now. Same for the AVS doors. Those are commanded to the full open position by the RSLS at the T-27 second point. If one of the doesn't reach the full open position by T-20 seconds an RSLS cut-off will be issued and the launch scrubbed.
The MMACS flight controller actually calls this out on the Flight Loop when it has happened ("All vents open") and the Flight Director usually replies with "Copy vents".
That's all very pretty and we could always "duct-tape" something together, e.g. like the AerojetDAP was, and it does many things. But when you want something else, or want to correct something... :facepalm:
I think we have a system that works for the most part, but IMO it's pretty stretched out, and some reorganization "under the hood" is needed to enable new stuff. Taking the AerojetDAP again as an example, it contained the SPEC 50 display. If we wanted to do a TAL or ECAL, we could not access that display to choose our landing site, as all that was inside the AerojetDAP and it doesn't run during ascent.
By me adding the SimpleCOMPOOL, organizing the guidance part and moving the display to "a better place", in the future it will be much easier to give full use to the display, although in the meantime nothing *new* is added so it seems like walking sideways. :shrug:

Why don't you implement the Kalman filter of the GNC MF base to get this value among others?

Also, this kind of question is why I asked about the MLS lately - many GNC sensors are still WIP, its getting time to finish them.

Here is a paper about the early state of things, maybe its good enough already for getting started:

I'm leaving navigation alone for now... guidance is already enough (plus a few touches in the FCS, plus the entry displays and HUD... and I'll try super hard not to touch the IDP for now).
