Using Step/Dir in Position Mode to Drive Spindle

After I bought a cheap chinese servo/driver combo and testing it, I am wondering on the interface to use with Linuxcnc.
Has anybody tried to implement the spindle just as a "normal" axis, so as step/dir and in position mode? Everybody uses velocity mode as far as I can tell. Position mode would give me the advantage of spindle orientation without too much trouble, at least in my mind. Thanks for the help! Maybe it is not a good idea, but if not then why so?

This has been done but is a bit complex if you need to support spindle orientation.

Typically the spindle is run in velocity mode when used as a normal
spindle and then changed to position mode when orientation is desired
(changing to position mode requires a home to index operation)
