There are some entries in the IANA db that are missing in this package. Specifically I am interested in model/stl, as I would like to fix up the Arch Linux AUR stl-thumbnailer package for Nautilus (well, the upstream source ideally). I would submit a PR adding just this but I am guessing you have a script that can update everything in one sweep and that sounds preferable.
There's no script apart from what's described in #4, but sync is now done with ec8c60e6b0b02b4af9081c6913746adb0da695f5.
