Proposed Response to FPDAM Part 1 BR-0001, et al

[Innovimax SARL]

Jesper,

The problem with versionning is that, it might be too late in the future,
and the argument that we don't "have a time travel machine" is still
sticking in my throat.

It's a too easy way to say: "Sorry we can't do anything, now it's too late!"

That's why saying that we are "unsure" is the least we could say since
probably in few months when we will seriously consider adding some more
precise mechanism, some or all will answer "sorry, too late, we don't have a
time travel machine"

Versionning is not about fixing existing problems as some of you suggests,
it's all about fixing future potential problems
