Removing the needs-implementation label as this MSC has both an accepted client and server implementation.

no, really:

@mscbot fcp merge

[mscbot]

Team member @mscbot has proposed to merge this. The next step is review by the rest of the tagged people:

• [x] @dbkr
• [x] @uhoreg
• [x] @turt2live
• [x] @ara4n
• [x] @anoadragon453
• [x] @richvdh
• [ ] @erikjohnston
• [ ] @KitsuneRal

Concerns:

• ~~Implementation cannot be tested~~
• ~~Authentication / rate limiting~~
• ~~Document why alternatives were rejected~~
• ~~The dir parameter is unclear/questionable~~
• ~~Context API doesn't appear to work with backfilling (likely spec bug)~~
• ~~Server doesn't appear to be able to forwards-fill over federation~~

Once at least 75% of reviewers approve (and there are no outstanding concerns), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

See this document for information about what commands tagged team members can give me.

Thanks :)

[richvdh]

I believe this is currently waiting for @turt2live to take a look.

[turt2live]

I don't think this concern is adding any value at the moment:

@mscbot resolve Context API doesn't appear to work with backfilling (likely spec bug)

... however there is still a problem with context and backfilling:

@mscbot concern Server doesn't appear to be able to forwards-fill over federation

(ref https://github.com/matrix-org/matrix-spec-proposals/pull/3030#discussion_r992858817 )

I think generally this is back to being ready for review from the wider team, barring any edits which need to be made to the MSC itself.

[turt2live]

I appear to be the only one with the concern, so in the interest of not blocking this needlessly:

@mscbot resolve Server doesn't appear to be able to forwards-fill over federation

we should, however, figure out how to fix this at some point.

:bell: This is now entering its final comment period, as per the review above. :bell:

[mscbot]

The final comment period, with a disposition to merge, as per the review above, is now complete.

[dhenneke]

@turt2live shouldn't this go into main?

[turt2live]

Older MSCs go to old_master due to branch conflicts, and will be brought over to main over time (usually when I'm at a terminal that can cherry pick)

[MadLittleMods]

Thanks all for the review! 😇

Next up is stabilizing the implementations in Synapse and Element where I made the experimental implementations.

Merged! :tada:
