The issue is that I dislike the overall mentality of just adding a bunch of language features. Things just seem to be dumped in each release and I think to myself "When I am going to use that?".

I didn't say no benefit. I said dubious benefit.

I didn't really want to get into discussing specific operators, but lets just use your date example:

   if (date is { Month: 10, Day: <=7, DayOfWeek: DayOfWeek.Friday }) { ... }

This following would do the same thing before the is operator:

    static bool IsFirstFridayOfOctober(DateTime date)
    {
        return date.Month == 10
            && date.Day <= 7
            && date.DayOfWeek == DayOfWeek.Friday;
    }

And then:

    if IsFirstFridayOfOctober(date) {
       ...
    }

I understand it is more verbose. But do we really need a new operator for this? I was getting on fine without it.

Each release there seems to be more of these language features and half the time I have a hard time remembering that they even exist.

Each time I meet with other .NET developers either virtually or in Person they all seem to be salivating over this stuff and I feel like I've walked in on some sort of cult meeting.
