I think this is a bad idea.

'color-correction' is designed to solve a legacy problem and allow
documents to opt in to what the spec has required all along (but
hasn't been implemented, at least partly due to lack of color
matching with plugins).  It's designed so that if we solve that
legacy problem (e.g., with changes to the plugin API) we can change
the initial value or potentially even entirely remove the property's
effect.  It's also designed to be the smallest possible solution to
the problem it's trying to solve, allowing authors to specify colors
in a globally-meaningful way, and thus hopefully the most likely to
be implemented.
