Those Mac clients who do not use nested folders do not seem to be affected. That is, I've already suggested to the Mac Mail user that he start Thunderbird, move all his mailboxes into the IMAP root folder, and then go on using Mac Mail. I hope that's what he has done.
There is a bug in Mail.app that it always assumes / as hierarchy separator and completely ignores server provided separator.
Not sure if anyone has created BUG to Apple about this. Atleast I have not.

So hm, I actually re-read the original post, and this is pretty weird, because I had to change the Dovecot separator from '/' to '.' in order to make macOS clients work with subfolders properly.
I never had this problem myself because only use folders, not subfolders. And it was pointed to me by another user, who relies on subfolders and had problems for some time - *maybe* from since around the time she upgraded to Catalina.
