I think this is entirely reasonable. It can be thought of as only one option,
which, if specified, means "create the necessary resources in this directory",
where "this directory" has a default. If the option isn't specified, then no
resource creation occurs.

If the resources are unmounted when BRLTTY dies, and the directory deleted (if
and only if it was created by BRLTTY itself at the start of the session), then
the user could kill BRLTTY, then restart it, in order to eliminate this
behaviour and the associated resources (file systems, device files, etc.) that
were created/mounted by BRLTTY.
