I suppose pulling support for 'never implemented' is OK.
Low usage is quite different.  If any document on the web
uses it and support is pulled, then that document is broken.
Hasn't Tim Berners-Lee said that one should not do this (assuming
the document was correct when posted)?

Also: how does one determine low usage?  There can be large archives
unknown to a given user and not found in search engines.
