as far as i know (and knew for almost 2 decades): dovecot can have the  
following filesystem-layout with maildir:

* every folder has three subfolders in filesystem cur, new, tmp
* every folder is flat under eg.: ~/Maildir with only one exception:  
INBOX, which is represented by 3 toplevel folders cur+new+tmp
* mailfolders have subfolders cur,new,tmp

stripping would be valid ONLY for INBOX itself, but not for its subfolders.
example layout:
