I think it absolutely makes sense. This is quite similar to what we have in Filter Effects. The other way around it doesn't make sense to have to different specs that try to address the same use case. Both done with a masking property (even if it might be called different). You can already try it in Firefox right now.

This is a different approach and it seems to be very interesting in the context of SVG as well (as paint sever for instance). However, at the moment it has noting to do with masking. Masks can take element() as input image and it is planned to do so.

Because the last draft of SVG 2 does a lot of changes to masking which seem to be helpful on HTML as well, it might be the time to discuss these changes with the CSS WG. I would like to avoid repeating the same mistake on masking that was done on transforms initially.
