Hi,

I support WG adoption of this draft.

It seems clear to me that protection for any constrained topology should
use/prefer same constrains if available (with possible fallback to base if
operator wishes so).

Flexible algorithm based topologies should be no exception to this.

And as a side note if using flexible algorithm solves real problems even if
the same problems could be solved with MTR to me this is a feature not a
bug to use simpler technology to accomplish the goal(s).

Cheers,
R.
