Agreed.  However (a liability of my snipping), Isaac mentioned his
intention of merging into a single AS, presumably inferring a temporary
workaround.  As an interim solution, though not a "good thing", it works
fine when judiciously tuned.

Not all *that* long ago, use of inconsistent AS was a very
effective/creative method for smaller entities that did not qualify for
thier own CIDR space to multihome using upstream space. ;)
