What does this mean in practice?  I see nothing about this in NEWS or
in the manuals, which makes me wonder how is this "more flexible".  I
guess there were some discussions, but neither the log message nor the
bug discussion mentions any other sources of information.  Could you
please point to those discussions, or fill the void by explaining what
additional flexibility do we gain?  This is for future forensics, if
for nothing else.

Thanks.
