It can coexist. Now, whether it should overlap the same device numberspace,
I'm not so sure.
Solaris, for instance, provides BSD-style (SunOS 4 compatibility) ptys named
/dev/[pt]typ[0-9] and so forth, but they aren't in the same device
numberspace, because the naming scheme is quite limited. In the case of
/dev/pts having its own device space, you could have as many nodes as you
want (or even a kernel fs similar to fdesc), without worrying about running
out of letters.
