A quick scan of what's after 0x10000 gives tons of "ancient" this and "ancient" that, various conscripts, and finally "Musical Symbols" which I suppose would be used by modern music software that wanted to use TTF fonts rather than its own rendering, and various styles of Mathematical Alphanumeric Symbols.
I don't know whether the CJK Suppliments outside of the BMP are for common use or only obscure use, but then there is CJK Compatibility Ideographs Supplement. If they are "compatibility" they must have been needed to match some existing information system.
