Interesting solution, but I have concerns and I wonder how this will actually work for you, long term.

I don't think that is what hidden means in the config. The path would not be visible in the client because it doesn't fit the maildir pattern of having a leading / for the name.

And that is my main concern. I think you will find that iCloud sync WILL, in fact, synchronize those settings across devices. If I were you I would set this up as a different account on your Mac (in Internet accounts), disable that account use on your iOS device and only have it enabled on your Mac and then it should not matter.

That should work, I would think, as long as everything in the chain is OK with symlinks (which is my other main concern with this).

I might set up my iOS clients with something like this that shows all the mail folders EXCEPT Archives on those devices.
