I believe that this was done by design during the rewrite of the
EM/xpinstall code for Firefox 1.5. The extension installation procedure is
now staged with a fallback at each stage and significantly more error
checking. The reason that all files in the extensions/{GUID} directory are
deleted was that some extensions would leave behind old files in those
directories that they shouldn't. When a newer version of the extension was
installed, older versions of these files were picked up causing mysterious
problems and js errors in these extensions. It was believed that a clean
slate would eliminate these hard to diagnose problems.

Yes, you should have put your persistent data in the profile or
profile/chrome directory. Mnheny, Launchy, CTB and most other extensions
that I have investigated do it this way.

No. It's just you not following recommended practices.
