Is this too big of a change?

Hi. We're working on 1.2.6beta2 and are proposing to make a change
that has somewhat more impact than we would normally make in a point
release and we'd like to see how much trouble it would create for
The OpenAFS and Arla community is working on support for somewhat more
native krb5 authentication to AFS. Servers will support the
encrypted part of a krb5 ticket sent with a special kvno as an AFS
token. It turns out that if you have a special krb524d this
improvement allows you to upgrade to doing krb5 AFS without any client
We're going to roll support for this change into the 1.2.6 krb524d.
The question is: how should we determine if we use the new style
tickets or whether we just issue krb44 tickets as before.
The AFS community seems ready to push fairly hard for upgrades to this
new technology and (when it is ready later, RXGSS) so we'd like to
help them by making the default for afs principals be the new
format--optimizing for future convenience at the expense of
transition-time inconvenience. We plan to default to the new format
afs principals with an exception list of afs principals that should
receive normal krb4 tickets.
This means that if you were to deploy 1.2.6 today, you'd have to
create an exception list for any afs cells your KDC serves.
Does anyone believe this is too much work for sites to do when
deploying 1.2.6? I'm much more interested in reports that this
actually would be a problem than reports of how this might be a
problem for a hypothetical third party or how I could do something
