Well, here are my thoughts on that subject.

First, historical.  The original MH people thought it was a good idea.
That doesn't mean we have to continue that, but I was reluctant to just
yank something out without a replacement.

Second ... encrypted messages are a little bit different than all other
messages is that they are an encapsulating type, where you have to decode
it to get the "true" mime type, and that decoding may require some sort
of user interaction, so you may very well want handle them differently.
It's fair to point out that we don't know what a potential %(encrypted)
function escape should necessarily do just yet; I am just thinking ahead.

I'll let you and Valdis fight THAT one out :-)
