Well, think about it - if you would try to do that, how would you ever
stop the watcher, as you just destroyed the unique ID (it's address).

Sometimes it does, sometimes it doesn't, but this is a separate question,
even for watchers where libev does not retain pointers you are not allowed
to destroy them, move them etc., without telling libev about it.

It's actually mentioned quite a few times, for example in "ANATOMY OF
A WATCHER" (which everybody should read), in the description of the
ev_xxx_stop function, ev_is_active, ev_is_pending, it's mentioned in
detail multiple times in "WATCHER STATES", and that's when i stopped
looking.
I am honestly a bit surprised at how you can miss it, if you really tried
to read the documentation :)
