Another alternative I just had to think about would be to register
both a v1 and v2 TVLV container while only registering a handler
for v2. That'd add just two or four extra lines of code with the same
result. The disadvantage would be a few bytes extra overhead for
dragging a v1 TVLV in the OGMs along.
Actually, I think I'd kinda like that as it has a reasonable
benefit-to-cost ratio. What do others think?
(And maybe such legacy multicast v1 TVLV could then safely be
obsoleted/removed in four years or after evaluating whether someone
still needs it.)
