Sounds more like you just introduced a new self-created problem that would require yet another workaround.. ;-)
Definitely wrong.
Appending .dir to directories and .folder to folder files keeps files completely distinct and name collissions are not possible.
But what was not clear from your mail, is what exactly you identified as "the problems" with standard Maildir++ setup?
Having regular files filenames beginning with a . is a no-go and flawed by design. Extremely error-prone No serious designer would ever do that.
Dovecot doesn't force you to use LAYOUT=Maildir++. Just use LAYOUT=fs and you can also specify a DIRNAME=<something that never exists> to avoid collisions with cur/new/tmp names. Actually, Dovecot doesn't even force you to use Maildir at all. Its own sdbox/mdbox mailbox formats are much more efficient if you don't care about using a standard mailbox format.
Even worse, both folders foo/bar and foo.bar both get the filename .foo.bar
Not with listescape plugin enabled. And if namespace separator is '/' as you seem to imply, newer Dovecot versions will give an error instead of silently translating foo/bar to .foo.bar (newer = probably last 5+ years or something).
