Why not? I was told the opposite: now that the feature is in JS natively, it can be used.

The Deno style guide encourages the use of `#prop` over `private prop` [0]. Other guides such as the Google TypeScript Guide discourages their use [1] for now because they are transpiled to slow code.

What I could conclude is: use `#` over `private` for runtimes that support them or projects that can target recent runtimes and browsers.

Probably so that tsc can transpile it differently for older browsers.
