Would you realy go through and kill them? I'd either just wait for them
to timeout - or restart the attacked service, if I can.

I agree, however, that ipfilter should imediately drop state for connections
affected by a new block added. (By magic done in userland, of course)

Anyway, to reiterate: if people think this functionality is usefull, I'd be
not opposed to adding it.
