Yes, thanks for clarifying.

I realise now that I lied about the behaviour that I was seeing.

I use the default tag:inbox search, but archive all the mails 'a' as I
read them, using other tags to keep track of things I want to come back
to.

That means that 'inbox' behaves the way I described 'unread' to behave
for me. I see the new messages as the old ones had their 'inbox' tag
removed.

Thanks,
