1. Is this specification needed to fill gaps in the XMPP protocol stack or to clarify an existing protocol?
Yes
2. Does the specification solve the problem stated in the introduction and requirements?
Yes
3. Do you plan to implement this specification in your code? If not, why not?
No. Maybe as an opt-in at some later point. I see the reason why one would like to delete messages one sent. I see extremely few use cases where I would allow third parties to delete messages they had sent to me. On the contrary I see multiple ways in which this can be abused or cause harm in other ways. I think the time limit can make the impact of those things a little less severe but on principle they are still there.
4. Do you have any security concerns related to this specification?
No. I have major concerns with the feature itself but none that can be fixed in the XEP or via technical means (aside from the optional time restriction that has luckily already made it into the XEP)
5. Is the specification accurate and clearly written?
Yes.
