I raised the issue and got the same response, i.e. agenda denial and refusal
to answer the substantive point.

Define "needed". If the standard of "needed" is "required 
to make the 
protocol viable", then this is not "needed". If "needed" means 
"anything we feel like changing, we can change", then the 
words in the 
charter are meaningless.


Needed means that the value of making the change is 
justified by the 
cost of making the change.

In this case the cost of the change now is much less than the cost 
will be in the future. This particular change was proposed multiple 
times during the development of DKIM (I was the proposer). 
Each time 
the pushback was the cost of making the change.

Really? I don't remember that. In fact, there was no backward 
compatibility issues at that time because the DKIM-Signature 
header/hashing was different than the DK signature/hashing. 
As I remember it, the chosen hash generation was different 
than both IIM and DK. And here we are two years later, um, 
rehashing the same decision.
