Opening a ticket to releng for clarification might help. In general,
releng asks *us* to let them know of which dates we want to have, so
next release, let's make sure we let them know in advance of what we
suggest.
Our need is to know the due date to submit our translations. The reason,
date looks important to me (and I think for all localizers) is because,
strings keep on changing even if there is a "String Freeze" date given to
the developers. Which basically increase our efforts most of the times to
complete the translations. So, if we know the last date to submit the
translations then we all can estimate our workload and schedule the
translations accordingly.
Right -- it'd be a good idea to communicate the above with releng and
put them up somewhere for future reference, for example on the Freezes
page [1] and on our FAQ.
