Technically nothing prevents this, but this will be pretty awkward since
client and server will need to convert to/from IDs (plus
wrapping/unwrapping the wl_proxy for the client) and there won't be any
type safety. In general it's better to have a request/event carrying a
single object which can be sent multiple times to accumulate a list of
objects.
