Thoughts on the FreeBSD ports/package system

While we have been working with FreeBSD packages for a while, it seems like the structure of how packages get built and distributed leaves a few aspects to be deserved. This issue describes our gripes in the hope that someone can help us find solutions.

* The FreeBSD base system and packages should feel like one consistent system, not like a "split personality". They should be upgraded together, e.g., when one upgrades the FreeBSD base system from 12.1 to 12.2 then all packages that require different binaries to work on 12.1 vs. 12.2 should be upgraded as well (e.g, Intel GPU driver). If the Intel GPU driver that is available in packages does not work with the base system, then this should be a blocker preventing the base system from being released. (In fact I think that Xorg and all GPU drivers should become an optional part of the base system because they are as essential to the operation of a graphical system as the kernel and basic command line userland.)
* This also means that for FreeBSD `-RELEASE` the packages should be equally "slow-changing" (not rolling release!), whereas for `-CURRENT` rolling release is acceptable
* It should be possible to use `quarterly` packages without the fear that from one day to the next a package disappears (it is ok if the old version of the package stays around until a new one is produced, but packages just going missing is not acceptable). In fact, isn't "quarterly" supposed to not change during the quarter? Users who want daily changing packages can use `latest`. This could be achieved by freezing a snapshot of `latest` at the begin of each quarter, and only allow _new_ packages to be added after this point but not to change _existing_ packages except for very urgent security patches
* As long as the point before is not solved, we are forced to use `release_X` packages (which get frozen at the time when the FreeBSD images are built). But there is no way to get new packages into `release_X` packages which effectively means that we can get new packages only after a quarter has passed (e.g., `falkon-qtonly` is not available in http://pkg.freebsd.org/FreeBSD:12:amd64/release_2/ but hopefully will be in `release_3`)
* We need to find a way to tell `pkg` not to touch/overwrite certain files (example: files in `/usr/local/share/dbus-1/services/`, [details](https://github.com/helloSystem/Filer/issues/65#issuecomment-946903675))
