I agree with you somewhat. I think my role as a developer/designer is to make sure that my forms work with pw managers. But I think encouraging users to use a manager should rest upon password managers. I can nudge them to use a secure password but the decision to write something like "please use a password manager" isn't usually my decision.
Also, let's admit it, unless you do something really crappy like remove copy-paste, forms don't exactly "not work" with managers. Most of the time, you don't have to do anything special and it would work. Some just take a bit more time because you have to cop-paste it and not autofill. But people who are already using pw managers don't just stop using it (or start memorizing their passwords) because one site can't be autofilled. They just copy paste it, at worst, they manually input it while looking at the password from their pw manager of choice.
My line about "supporting" it is a bit off. I used the wrong words. It goes to say that you should support it. Again, you have to do something really out of your way to completely block off password managers from your forms so really, I think the norm is that they support it. My thought goes more along the line of whether I should be the one to adjust when the form works on some pw manager but not on another or when the pw manager can handle other sites properly and not mine. "Working" and "handling" here means it can be autofilled (most of the time).
