Because if I did that I'd have to patch any sieve webinterface I use
to let my users edit their filtering rules to include the necessary include.
My patch allows me to keep the spam-filtering policy seperated from any
user-defined filtering rules. I want to give my users a single-click option
for choosing between "File junk into the Junk folder", "Flag Junk" and
"Don't do anything". With my patch, I just have to change the "sieve"
annotation for the user's inbox - otherwise, I'd have to parse his sieve
script and modify the include - with the risk of somehow messing up his script.

Additionally, at least for me, my patch seemed like a natural extension of
the already existing sieve annotation for global mailboxes.
