Yeeeahh! I got it.
For those who have the same problem:
Then, I took a look in conf.d/20-imap.conf and found the following:
# Workarounds for various client bugs: # delay-newmail: # Send EXISTS/RECENT new mail notifications only when replying to NOOP # and CHECK commands. Some clients ignore them otherwise, for example OSX # Mail (<v2.1). Outlook Express breaks more badly though, without this it # may show user "Message no longer in server" errors. Note that OE6 still # breaks even with this workaround if synchronization is set to # "Headers Only". # tb-extra-mailbox-sep: # With mbox storage a mailbox can contain either mails or submailboxes, # but not both. Thunderbird separates these two by forcing server to # accept '/' suffix in mailbox names in subscriptions list. # tb-lsub-flags: # Show \Noselect flags for LSUB replies with LAYOUT=fs (e.g. mbox). # This makes Thunderbird realize they aren't selectable and show them # greyed out, instead of only later giving "not selectable" popup error. # # The list is space-separated. imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags
As we have a very heterogenous infrastructure, with Mac OS X Thunderbird, I added the missing 2 TB options (I also have LAYOUT=fs on the public folders) and restarted Dovecot. Now it works without showing obscure messages - it just deletes a subfolder as a user would expect! :-D
Of course TB must be still set up to delete immediately.

Step 1 accomplished: It worked.
So, it's a TB bug? Some known workarounds?

I've already read about configuring Thunderbird to delete immediately - which I did. But it still doesn't work.
Step 1: Verify that it really is a DELETE command that fails and that the returned error is "Permission denied". For example:
telnet localhost 143 a login username password b delete Folders/test01
