Ian Bicking: the old part of his blog

I agree that a standard of the more high-level tasks would add much to the usability, yet it makes the standard harder to implement for the maintainers of web-frameworks.

Maybe it would help to see this as a sort of first stage standard, which is later extended to a wsig 1.1 that includes some more features. This way wsig is still easely implemented, yet it offers a specific way to the next step, as soon as the respective maintainer has some more spare time.
