I have no problem with it.
But there's something I was thinking: Shall we distinguish "withdrawn without finalization" and "obsoleted/superseded by
newer srfi" more prominently? The former was purely a historical record. However, there may be implementations that
incorporated once-finalized srfi. The implementer may not track srfi development closely, then it is a bit difficult to find
which have been obsoleted when he comes back to srfi site several years later.
Currently the "superseded" information is available on the srfi document itself but not on the index nor front-page (those two
only has "see also" links.) It may just suffice to change these links to "supeseded by". It also help if we can filer by
superseded status. Adding 'superseded" status requires changing srfi process document, so if it's too much, it's ok
just to have a feature in srfi index site that allows searching by superseded flag.
