[skriss]

The HTTPRoute docs have several references to
an "Attached" condition, however this condition
does not exist for routes. Replaces these

condition.

So from what I can tell, this appears to be right: we've had this wrong for some time as the Accepted condition exists for HTTPRoute but not Attached (which is only a Gateway listener condition elsewhere). Approved, but I would like another maintainer to just double check me and give the LGTM because I can't shake the feeling like I might be missing something 🤔

[youngnick]

This change is one hundred percent correct as per the current spec, but I'm currently working on a status rewrite which proposes we move to Attached everywhere. So maybe this should wait until I finish that up and we discuss it?

This content likely needs to be revisited now that #1383 has merged.

So this was just trying to fix a bug in the v0.5.0 spec/docs, but I guess at this point it's probably missed the boat for inclusion in v0.5.1? If so, and the broader v0.6.0 conditions changes will cover this, then we can just close this one out and live with the v0.5.x docs bug.

[skriss]

Rebased in case we want to include it in v0.5.1, if not, and will be covered by larger v0.6 changes, feel free to close.

[robscott]

Thanks @skriss! If you follow up with a cherry-pick PR into release-0.5, I'll add it to the v0.5.1 changelog.
