Atom + Member URIs

We have been having an interesting discussion here regarding the AtomPub
protocol.

Is it ok to change the MemberUri on a put? EG: Return a Location header and
then point to a new MemberUri?

Example:
You have
/feed/0

you put new data

it returns
Location: /feed/74

The feed is updated and no longer does /feed/0 show up in the feed (top
entry is now /feed/74).

There are some advantages (and disadvantages) to this mechanism and I am
not sure if its allowed or not.

The big thing I see as it breaking is people that want to bookmark all of
MemberUris. Is this a good idea in the first place? This could be worked
around as well by returning a moved with the new link if you use the old
Uri. There is already an edit rel link in the feed itself.

That said most people I see using atom are directly bookmarking their
MemberUris and this would probably break them and is as such a meaningless
practical discussion. But is it protocol compliant?

Cheers,

Greg
