I understand that and I agree. I'm just trying to list up pros and cons of Florian's proposal, I said "weak" in the first two reasons and that includes this one too.

As far as I think, I came up with 3 weak reasons to keep the current syntax. If you don't want to include this even as a weak reason, that'd be 2 weak reasons.

On the other hand, the only reason to change the syntax is "the same thing is doable by @text-transform rule," in a lot lengthy way, and which is still under discussion.

As I said, I'm totally fine to change the syntax if it is reasonable to do so, or the proposal is strong, so I wanted to find reasons to change but without luck.

If we don't come up with any other reasons behind this, I'd prefer keeping the current syntax. Again, it's not strong and I'd love to hear any other good reasons.

EPUB behavior is tied to early working drafts of CSS specs.  As with all CSS working drafts they are subject to change, including this property. 
This issue should be decided based on whether combining transforms would restrict future behavior or not and *not* on what EPUB has or has not included in their spec.  There is absolutely no obligation that the CSS WG support a specific syntax in a specific *working* draft!!
