[Libreoffice] default ODF encryption/checksum algorithms changed in master. Good thing ?

Since 5dd2784030e00fa1857b30ee8c5da62e221bfd32 (inherited change) the
default encryption and checksum algorithms used in our .odt export
changed, e.g. sha1 to sha256. They changed for settings of "ODF >=
1.2".

What it means in practice is that encrypted document exported from >=
3.5/3.6 won't be openable in older versions, e.g. <= 3.4

There is a UseSHA1InODF12 and UseBlowfishInODF12 setting which is
currently disabled.

Such a change shouldn't go unnoticed anyway. So...
a) is this a good thing that should be welcomed, with a "users using
older version of LibreOffice/OpenOffice.org should upgrade and/or hassle
their vendors for patched versions with support for these backported"
b) a bad idea ?
