Relative import paths need explicit file extensions in ECMAScript imports

[FyiurAmron]

While trying to use with a Node16+ module type app, I get the following (e.g.):

error TS2835: Relative import paths need explicit file extensions in ECMAScript imports when '--moduleResolution' is 'node16' or 'nodenext'. Did you mean './..\google\protobuf\timestamp.js'?

import * as dependency_3 from "./..\\google\\protobuf\\timestamp";

Obviously there are workarounds to allow this to interact (defining a separate project etc.), but is it possible to have a boolean flag that would either emit those as "filename.js" or, by default, "filename" as it did previously?

(unless I'm missing something, it's impossible now... at least I couldn't find any such option yet)
