[Mailman-Users] Archiver not stripping [foo] prefix

Mailman 2.05 doesn't seem to strip the [foo] prefix from Subject: headers, resulting in an archive that looks like this:

 * [mems-talk] DRIE service?   Lihua Li
 * [mems-talk] Developing high Aspect Ratio SU8 Photoresist
   Feteih@aol.com
 * [mems-talk] Information   Mohammad Abbas Khan
 * [mems-talk] Bonding PDMS to SU-8   Jamil El-Ali
 * [mems-talk] Polyimide processing   gururaj shenoy

I vaguely recall Pipermail doing this way back when. Before I write a patch implementing it, can anyone remember if there's a reason it was taken out?
