The lifetime design enables us to just store references for shared ownershi=
p,
rather the needing a reference count, so it seems reasonable to remove thos=
e
blanket impls.

We could keep them a little longer until pin-init has self-referencial supp=
ort,
but on the other hand they don't enable anything and are just for covinienc=
e, so
I'd rather drop them.
