That is one use.  That is not the only use.   I'm not arguing that we
don't support Blowfish at all.  I'm saying that we should also allow
saving with AES, as allowed by ODF, and as required by regulation for
many users.

Your use of the word "unilaterally" is rhetorical nonsense. As I said
before, I favor having option for the user to select the encryption
method to use.  We should try not to 2nd guess our users' preferences
and offer only lowest-common-denominator, one-size-fits-all solutions.
   We should try to provide configuration options for reasonable
alternatives, especially where we know different user populations will
have different preferences.

There are better ways to pity the poor user at home with a 3 year old
version of OOo.  For example, making it easier for them to know that
their best option is to save the document on ODF 1.1 format.  That
solves this issue, and several others.
