[Dovecot] Wish-list: X-Delivered-To headers generated by dovecot-deliver

[Andrzej Adam Filip]

Would it be sensible/"cost effective" to make dovecot-deliver generated
X-Delivered-To header(s) based on command line parameter(s)?
[after striping such existing headers, before consulting sieve]

I need it to:
a) *clearly* mark POP/IMAP account fetched by fetchmail
   [with fetchmail using directly dovecot-deliver in --mda option]
b) cleanly implement "shared mailboxes" with MTA such as sendmail
   that can be easily forced to generate "one header per one recipient"
   [AFAIK]
