If you're creating artistic text using SVG paths, then even if you add invisible text for accessibility purposes, it's not going to have the correct set of baselines for alignment. If you're creating icons, then a random bit of invisible text isn't going to be useful for either accessibility or defining baselines.  So I wouldn't want to defer to embedded text for baselines unless that's the actual visible text that we want to align.

That said: If CSSWG decides that there isn't a need for a general CSS property to define baseline tables for a replaced element, we can discuss SVG-specific ways of defining baseline tables in SVG-WG (or SVG-CG).
