Not being a DD, much less a policy maintainer, I didn't want to overstep
my bounds.  :-)  There was at least one person in that thread who
thought non-main dependencies could be listed first.  However, I agree
with you, and would prefer to mandate that the first alternative
explicitly be the default and that this be required to be in main.
