The open slave sides should (it would be strange if they did not).
The master side does not need to have one (and it does not).
To answer the question differently. If you don't need the functionality
of being able to open a particular pty by name, you can remove
/dev/pty?? and /dev/tty?? [ahem, not literally because /dev/ttyE0
is not a pty, but you get my drift].
