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?
