Longer-term use has, at least, operational import, for access to the
DKIM key and for access to the message in its signed form. Neither of

Could you be any more vague? ;-) This does not say anything quantifiable.
How delightful. Attacking with creation of a post-hoc requirement.
Could you be any less constructive?
ps. yes, I could be. and that assertion demonstrates it.
Surely you don't mean to say that keeping DNS RR for, say, three months
instead of two is costly?
The operational procedures for ensuring longer-term data reliability and
accuracy are different than those for shorter-term. If that concept
isn't clear to you, then you need a longer discussion, which you've made
clear won't be constructive to have with me. That's ok, because it
should not be necessary in the first place.
Also, DKIM signatures matter while messages
are in transit. Once a message reached its destination and has been
processed there, who is left to care?
Apparently you are not familiar with post-delivery efforts to validate
DKIM signatures. That explains a lot.
And what good would the x-tag do
to reduce operational cost, in your opinion?
Perhaps you missed the small fact that I did not argue in favor of, or
against, continued use of this feature, other than noting that adding
features adds complexity.
