We used to document it but the document was always stale. ttyPIC sounds fine providing nobody else is using it (and I don't think they are but grep is your friend). We enforce the rule because in the early days lots of people re-used ttyS for their chip. Then their chip grew an external bus or turned into a SoC and a 16x50 got added and it all broke. ttyPIC ought to be fine because even if you get new PIC devices with a different uart you aren't likely to have both of the PIC cores on the same device.
