No. KMS names ("DP-2") cannot be used for a reliable identifier.
wl_output.name specification states:
The name is not guaranteed to be persistent across sessions, thus cannot
be used to reliably identify an output in e.g. configuration files.
See the discussion at [1] for more info. To fix this, we'd need a new
wl_output event and a new KMS property.
