Of course _perma_links are not supposed to change. But I think the
point that Mark Pilgrim makes, and one that I agree with, is that
principal does and will collapse in real-world tools.
Migrating between CMS systems, rebranding to a new domain name,
switching advocacy to support the ‘no-WWW’ movement? All perfectly
likely and reasonable things to do, which CMS's generating permalinks
have not been designed to support and a problem which, regardless of
the ideal, many (most?) authors simply won't account for.
There may not be a solution to this. Fitting a tag URI into page
content seems clumsy for sure, and those same CMS systems that make
permalinks less-than permanent are publishing dynamically generataed
permalink URLs as IDs all the while. I'm not sure that we're in a
position to ‘fix’ the problem. But I think we should try to exhaust
the non URL options thoroughly.
