Search engines either do not spider or do a very poor job spidering URLs containing session IDs. They also make a URL non-user friendly to remember.

True, but there are very few reasons to put the SID in a URL when using sessions - and very easy to rewrite the legacy BBs and other apps that are using this scheme.
