Marked as such.

It is not, marked as such.

/var/lib/dpkg/info/mailman.config contains:
--8<---------------cut here---------------start------------->8---
# This script will be invoked by apt-get 2 times in a row, once when
# preconfiguring the package and a second time just before running the
# postinst script.  OTOH when installing the package with dpkg or when
# reconfiguring the package, it runs only once.
#
# It scans all mailing lists on a system for used languages which may
# be quite time consuming on systems with many lists; hence we better
# avoid to run that scan twice in a row.
# 
# The debconf template mailman/used_languages holds the result of the
# scan but is never presented to the user, instead its scanned flag
# indicates if it holds a fresh value and is reset by the postinst,
# while its seen flag is mainly used for cosmetical reasons to mark
# processed values in debconf-show output.

db_get mailman/used_languages || true
used_languages="${RET}"
db_fget mailman/used_languages scanned || true
scanned="${RET}"

if ! which list_lists >/dev/null 2>&1; then
  # For 1st time installers there is no used language.
  db_set  mailman/site_languages "en"
  db_set  mailman/used_languages ""
  db_fset mailman/used_languages scanned false
else
[...]
--8<---------------cut here---------------end--------------->8---

I guess that at installation time the if is true (there is no list at
all) and thus mailman/site_languages is set by default without taking
into consideration the interactive or preseeded choice.

Thx, bye,
