Should `deno_emit` output ignore comments like `deno bundle`?

[yacinehmito]

I am in the process of back-porting tests from deno bundle to deno_emit, and I found that we explicitly ensure that the output of deno bundle contains the following:

// deno-fmt-ignore-file
// deno-lint-ignore-file
// This code was bundled using `deno bundle` and it's not recommended to edit it manually

Is it desirable to implement something similar for deno_emit? If not, why? If so, should that be configurable?

I think that can be added by people if they want it in the output. That said, probably it creates some complications with source maps so maybe it should be handled by this crate? Or maybe it can be configurable?
