Typescript intellisense does not recognize 'delete'd attributes

[Barbiero]

Whenever you deletean attribute from an object, I'd expect intellisense to recognize that said attribute was removed.
Example of the problem:

The expected behavior would be for the autocomplete feature to NOT show the date attribute. Furthermore, if I were to call anything over said property(say, example.date.toISOString()) it should warn me of the undefined call. deleteing an attribute from a class/interface that does not define it as an optional attribute should also be an error IMO, though I don't know how feasible that is.

Either way, VSCode(or the typescript language server?) has no support for the side effects of delete atm.
