The rationale for missing includes was the same, when things go wrong it's usually obscure enough that problems only raise with build systems that have visibility restrictions. Hence I am not sure if this extra step provides enough value.

Agreed, making alt+enter work in these cases would be useful, and last time I checked it is actually working. I tried with this patch, and it still gives people a way to preview and selectively apply these edits. So we're actually not taking away the functionality completely, but rather putting this behind an extra shortcut :)

Can you check if it's still broken for you ?
