Any chances that opening a root shell into the modem can be used to grab the closed firmware, reverse engineer it, then swap with an open source one? I mean it's not just about security but also being able to implement nice things to have running and connected while for example the phone operating system sleeps between calls.

No need to actually do the re work(at least re the whole firmware), if you google a little bit you can find a leaked source to a firmware related to the modem in pinephone. look for mdm9607, mdm9x07, mdm9207. Also, some devs actually managed to replace the linux part of the firmware with linux build from source recently. I think they're trying to get mainline linux running now

There's also privacy. If someone's reverse engineering that modem, I'm curious what all is running on there, if it makes any connections other than what you ask for, and who it talks to, and what is said.

The firmware is already on github and the pinephone devs have mostly redone the Linux part to be less crappy.
