Hi Lars,

thanks for adding me in Cc.

Browser speed is tipically dominated by the internet/web server
bandwidth and it's therfore very variable.  Users will hardly notice if
a page loads slower because the cache was removed and complain, this is
indeed not the case for Emacs as program.

Also given the XDG spec definition I'm not sure this move would be the
right thing.

Best Regards

  Andrea
