I've never heard of that kind of agreement. Want on its own isn't enough
but *something* has to Want the target for the After to have any effect –
otherwise the After would remain a a no-op if nothing pulls the unit into
the transaction.

Whether the Wants should be in the "provider" or in the "consumer" is kind
of a case-by-case decision. Something like network-online.target contains
(Wants) actual services so it has to be Wanted from the consumer (as
there's no point in having it started when there are no consumers trying to
order After it). An order-only target could be Wanted from the provider
instead.
