With a few thousand users, I find that only a relatively small number of them has personalized procmail filtering set up. Still, that "relatively small number" may amount to a hundred procmailrc files or so. The users that wrote up a filter for themselves typically are power users, and their procmail recipes can be involved, so say the least.
There is a flip side to that argument: procmail has a fairly high learning curve, because the "recipes" are actually a terse programming language. Even though procmail has been around for a long time, there are no decent [web] editors for recipes (yes, there are some, but not standalone), so very few ordinary users take advantage of them.
The whole point of SIEVE was that it was a [mostly] capable, easily scripted language that *ordinary* users could employ. Asking your power users to rewrite their procmail recipes in SIEVE, so that a much more significant percentage of your entire user base could have the ability to use server side filtering, it entirely reasonable, IMNSHO.
