Most of the comments have questioned the "cost" of adding
2 ADs to the lucky number 13.
However, there are a other large numbers to consider.
For example 26 and 24 - the number of WGs in the transport
and Internet areas, respectively.
I have never seen a senior manager in a commercial enterprise
to whom 26 subordinates, each responsible for completely distinct
disciplines, directly report.
Decreasing the number of WGs per area to a number that
can be reasonably managed and technically lead by the AD
is one of the advantages of the proposal.
And this will still leave a manageable 15 members in the IESG.
