3696: vscode: more type safety r=matklad a=Veetaha



3698: Consider references when applying postfix completions r=matklad a=SomeoneToIgnore

Sometimes my RA debugging workflow breaks because `.dbg` is applied to the variable that is used later in the code.
It's safer to consider the refences to avoid this for completions that may trigger the move.

3703: Don't try to enable proposed API's on stable r=matklad a=matklad
