Files in /usr/share/misc

While browsing the filesystem, i found the folder /usr/share/misc and now i am curious, what kind of files and why they were put there.

The list on "13.0-ALPHA2 stable/13-f76393a63" looks like this:
-r--r--r--  1 root  wheel     3170 Jan 24 09:18 ascii

There are
- some more, some less technical "lookup" files, like:
ascii, birthtoken, flowers, iso3166, iso639, latin1,...

- some FreeBSD project related files, like:
bsd-family-tree.dot, committers-*.dot, organization.dot
These would better be part of the documentation.
BTW, on 12.x they are out of date: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251701

- some configuration an scripting examples, like:
init.ee, gprof.callg, gprof.flat,...
IMHO better placed in .../examples

- development(?) related files, like:
pci_vendors, scsi_modes, usb_hid_usages, usbdevs, windrv_stub.c
I don't know if these files are used during build-/runtime

- some files which are used during (build-?/)runtime:
magic, magic.mgc, termcap, termcap.db
Shouldn't these be in a more specific place? They are pretty static, so the "var" part in /var/db does not fit,
but services.db is located there, too.

- is the fonts folder in base, or did some port create it? I'm not sure.

What is the history behind /usr/share/misc?
