Not really, no, sorry. You could possibly make case for adding some ABI
to libwayland-client to help identify the wl_display, but since you
already wrap the wl_display in a C++ object anyway, you could just have
an id field there.
There doesn't seem to be anything helpful in wl_proxy. It wouldn't be
unthinkable to add wl_proxy_get_display() to return the associated
wl_display. Knowing that a thing is a wl_proxy, you could already
inspect the private fields to find out the wl_display in a debugger.
