I don't think it matters all that much if an axis is rotary or linear.
There isn't anything to stop you setting the U axis scale such that it
rotates an effector in degrees.

Teach programming isn't super well-explored, I don't think. But there
is a sample script:
https://github.com/LinuxCNC/linuxcnc/blob/master/src/emc/usr_intf/axis/scripts/teach-in.py
With a minimal manual page:
https://linuxcnc.org/docs/2.8/html/man/man1/teach-in.1.html
As it stands the script only records X, Y, Z. But as it's Python
expanding to more would be trivial. It would also be relatively easy
to have it output actual G-code programs rather than a position list.
