Well, I don't know what version 2 will look like yet :-)

I will add a dispatch rule that forwards version 1 specifically to my
current handler module.

Then I can deal with the choice of approach for version numbers when it
is time to do that new version.
Future me is going to hate present me... but present me will document
the considerations as comments.
