Unsolicited speculation: I wonder if this is related to your hiring woes? I have vague memories of seeing research along the lines that marginalized groups are less likely to apply to positions that do things like "Want 10 years of Go experience". Of course not everyone already knows "the big secret" and maybe (some?) marginalized groups are less likely to know it.

I'm pretty sure I've seen lively debate on HN about this practice, as well, though I wouldn't know what keywords to search for. It's definitely not universal in the industry, or at least it's a continuum. An example I remember recently seeing of a posting on the lower end of the "requirements" spectrum is Mighty App[2], where the list of posted requirements is two items long. I think HN user 'tptacek has written about taking this even to the extreme of having no posted requirements, and doing all candidate qualification via a practical exercise.

Of course if you go that route then you might make the screening phase more difficult. You'd also have to convince Recruiting/HR to go along with it.

[1] After a month at my first job in the industry (I came from academia) I idly checked out the job listing for the position I was then holding, since I hadn't come in through a job listing but rather through a recruiter. There were something like eight "requirements", and I held exactly one of them (a PhD).
