First, ff it wasn't clear, I was suggesting that I would add this to
Zope3.

So, today you use <a tal:attributes="href foo/@@absolute_url">

With my solution, if you would want to change the way the absolute URL
is generated for foo, you would register an unnamed view providing
IAbsoluteURL for foo.

After that when you use the above line, your IAbsoluteURL view will be
used instead. Nothing would be changed, just instead of having to
register two views, when named and one unnamed, you'd only have to
register one unnamed.

So nothing would change for you, apart from not having to register two
views.
