Thanks for the hint.
But it seems to be ignored. :-(
I tried it with a .forward of:

| "/usr/libexec/dovecot/dovecot-lda
-omail_location=maildir:~/Maildir:LAYOUT=fs"

and postfix logs:
... status=sent (delivered to command: /usr/libexec/dovecot/dovecot-lda
-omail_location=maildir:~/Maildir:LAYOUT=fs)

... but it still delivers to the default
(mail_location = mbox:~/mail:INBOX=/var/mail/%u)

Per-user configuration with userdb is static, you have to configure the
mailbox format for each user. However, if you'd like to give the user
the ability to switch between mailbox formats, dynamic detection would
be useful...

Right, that is overridden. You could use 
"-onamespace/inbox/location=<location>" instead.

Yesss! :-)
This one works great for me and is very useful for smooth migration from
mbox to maildir:

dovecot-lda.sh:
-------------------- 8< --------------------
#!/bin/bash

args=()
if [ -d "$HOME/Maildir/INBOX" ]; then
  args+=("-onamespace/inbox/location=maildir:~/Maildir:LAYOUT=fs")
fi
exec /usr/libexec/dovecot/dovecot-lda "${args[@]}" "$@"
-------------------- 8< --------------------

Thanks for your help!
