CSS and HTML do not respect version switches. I.e. there is no way for a
document to say "I am CSS 2.0 and HTML3" and get the behavior specified by
CSS 2.0 and HTML3 instead of whatever the latest specs say. When CSS or HTML
specs change, we change the behavior for *all* documents.

(There is a "quirks mode" switch but it doesn't map onto spec versions and
we are not adding to it.)

SVG transformations are often used in current SVG documents, therefore

Future recommendations need to be compatible with current recommendations,
or at least we need to be confident that any changes will break only an
insignificant amount of Web content. This is the way the rest of the Web
works, and SVG should be consistent with that.
