I'm hoping this is largely uncontroversial: @mscbot fcp merge |

Team member @turt2live has proposed to merge this. The next step is review by the rest of the tagged people: No concerns currently listed. Once a majority of reviewers approve (and none object), 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 info about what commands tagged team members can give me. |

Implementation: matrix-org/synapse#5930 |
|
super confusing to have an msc which patches an existing msc... |
|
the content of the patch however is ok |
|
agreed, however this is what our process calls for :( Something for the retro I guess |
|
Could you add a note at the top of the MSC to say that it was amended by MSC224 please? |

| In order to allow client implementations to determine if the homeserver they are developed | ||

aiui it's not really the fact that the HS supports being given the token (it would just ignore it if not) but more that it supports passing the token on to the IS?

Synapse makes angry noises when you supply id_access_token when it doesn't want one. But yes, that's another way to say it.

it probably shouldn't, but it's not exactly in the wrong here. Matrix doesn't say that a client can send unknown fields to endpoints, but it also doesn't say you can't. Synapse in this case I'd count as compliant, albeit annoying.
I can add some words about the flag being about supporting the field though, if wanted.

the field is in the body of a json post? I think it's fairly key to the extensibility of the protocol that servers don't complain about spurious fields. Anyway, this is OT here, I guess: I'm not really looking for a change if what it says is accurate currently.

I'm sure you've thought about this and I have no real desire to get involved with the bikeshed-painting, but it might be useful to record the rationale for choosing m.id_access_token rather than (say) m.authenticated_is_api or m.is_api_v2?
There was a problem hiding this comment.
I've thought about it no more than copying the flag out of a synapse PR. I don't really know the rationale for picking the flag we did, but I also don't want this to be a bikeshed problem. The path of least resistance was very much abused here.
I'd definitely be in favour of m.identity_api_v2 or similar to avoid is.

I'm jumping this straight to merged because there's no tangible requirement for this MSC to actually end up in the spec. We do not spec these flags because we expect that people will use the spec release as a detection for support. MSC2140 has its own status to worry about independent of this MSC. |

This proposal is an amendment to MSC2140 which was missed during review. A new proposal has been created as the change is major enough.
