[exim] filters in future releases?

Hello,

Sorry if I am all wrong but I thought someone had mentioned a while ago
that in future exim releases filters would be dropped. I am about to
prepare some filters acting on a combination of sender and messages
subjects and thought I'd ask whether filters are really soon going to
become obsolete. If so, then what should I use instead?

Just in case someone suggests, I do not want to use procmail...

Thank you in advance!
