No it is not. The goal of the test suites is to improve interop.  To
help encourage this, tests are required for various W3C publishing
milestones, but that is a secondary and less important part of their
purpose.  Attempting to place W3C publishing requirements over helping
interop is a complete inversion of priorities which is not acceptable.

When necessary, we can obtain exceptions to W3C publishing
requirements; we can't obtain exceptions to interoperability.  Please
don't suggest things that stand a good chance of hurting interop;
making tests require invalid behavior is one of those things.

However, we are not, we are working on CSS-Syntax and those tests need to be in CSS-Syntax and the CSS 2.1 tests need to be left alone as much as possible.

The only unfortunate this is we have not gone back and put notes in those CSS 1.0 tests. Here we have a chance to make things better for CSS 2.1 by adding in a note and link to the newer test.

"Making things better for CSS2.1" is a non-goal, except insofar as
some sections of 2.1 haven't yet been superceded, and so 2.1 is still
the definitive spec for those features.
