Agreed.  And you are making my point: once you have smaller format,
there is no reason why any energy constrained device would ever have the
original format.

Which is why, if this is useful, then we should have one format only.
It doesn't hurt non-energy constrained, non-MTU-constrained devices to
use fewer bytes.

I don't know that the ML concluded that.
I thought that most people felt that we should have one format.
