In my experience that seems to be exactly what they do do—rely on the
OS to provide image decoding (as with other AV media).
I say this because changes that had occurred in the OS (such as
adding JPEG-2000 support) are immediately picked up by my browsers.

WMV 9 is supported on the Mac OS via a (legal) download, so only
Linux would get screwed. Once the download is installed, every app
that uses QuickTime (including apps that have their own codecs too,
such as RealPlayer, VLC) immediately gain the ability to play WMV
files. Same is true for the Theora codecs from xiph.org.
I assert that any codec written by a browser vendor and available
only within that browser is user-hostile (due to lack of system
ubiquity), likely to be slower and buggier than the free decoding
component written by the codec vendor themselves, and detracts from
the time available for implementing other browser changes.
