Yes, but the problem is that CSS minifiers convert "scaleX(1)" into "scale(1)" and "scale(0, 1)" into "scaleX(0)", which prevents using both "scale" or both "scaleX" in this case if you're using a CSS minifier. See this code for example: https://github.com/cssnano/cssnano/blob/04bd16e9de5e2d4409fef74034edb7534cd9e457/packages/postcss-reduce-transforms/src/index.js#L93-L123.

I believe that this CSS minification transformation is valid since these I'd expect for these forms to generate the equivalent matrix (i.e. "scaleX(0) == scale(0, 1)" and "scaleX(1) == scale(1, 1)"). Please let me know if that's not a valid CSS minification transformation and I can file an issue with the relevant CSS minifiers.
