MM 1.8.x will come with the new "filter-policies" logic, for which I totally suggest adding some new configurability. Right now the filter policy is an option that can be given to MM when it's started, and is "DEFAULT" by default. See:
https://www.freedesktop.org/software/ModemManager/api/1.8.0/ch03s02.html

This is already available in 1.7.990 (1.8-rc1), and I believe it's very interesting in buildroot as most people building custom systems using buildroot may already be using a single set of modem devices to work with, so the whitelist-only filter is very convenient to avoid MM fiddling with non-modem TTY ports. For those expecting a lot of different devices, the new "strict" policy would probably help as well, which is what we'll be suggesting to distributions (e.g. this was developed after discussions with Debian).

And regarding dates for a 1.8 release... not yet :)
