I wouldn’t be surprised if that there’s room for discussion on evolving the exact language there.

There’s obvs a nice element to the strictness there, tho practically I’m not sure it’s something that implementations will follow, and its not something that Starlette chooses to abide by.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",463544206,"Populate ""endpoint"" key in ASGI scope",

(Ie. ""endpoint"" doesn't need to exist at the point that the middleware starts running, but if it *has* been made available by the time an exception is thrown, then it can be used.)

Starlette's usage of ""endpoint"" there is unilateral, rather than something I've discussed against the ASGI spec - certainly it's important for any monitoring ASGI middleware to be able to have some kind of visibility onto some limited subset of routing information, and `""endpoint""` in the scope referencing some routed-to callable seemed general enough to be useful.
