Sure for the old commands everything is still in the lower 32bits, this
has the nice property that we don't need to duplicate all the code for
v1 and v2.

I don't think you need to duplicate anything, just have a little
function that maps from the free-form v2 commands and flags to the
v1 field.  Preferably including a mapping of all unsupported ones to
a catchall unsupported command and flag each to indicate that the
trace includes something only visible with v2.

I see your point, let me cook something.
