I support adoption of this draft.

However I really do not think that what Flexible Algorithm offers can be
compared or even called as Traffic Engineering (MPLS or SR).

Sure Flex Algo can accomplish in a very elegant way with little cost multi
topology routing but this is not full TE. It can also direct traffic based
on static or dynamic network preferences (link colors, rtt drops etc ...
),  but again it is not taking into account load of the entire network and
IMHO has no way of accomplish TE level traffic distribution.

Just to make sure the message here is proper.
