Yeah Boris, if Dario let's you communicate here, it'd help with credibility if the English level would be perfect, it's "it's an old hat", I dgaf if people will hang me for this, I think I am right. My hill and all that.

And to recommend auto made to devs is absolutely crazy.

Have a nice day

I disagree. "Old hat" here is an adjective meaning old-fashioned, not a noun requiring an article.
