I don't think so.  Note that we're talking about *static* functions 
here. WebIDL says this about static functions:

    A static operation is one that is not called on a particular 
    of the interface on which it is declared, and is instead 
    with the interface itself.

When such a function is specced as...
 * changing state in a way that influences behavior (as with houdini 
 * depending on state (as with `CSS.supports` in the face of possible 
calls to `registerProperty` which should influence supported styles)
...I don't think the WebIDL spec or Houdini Properties & Values says 
anything right now about where that "static" state lives.   WebIDL 
talks about state associated with *instances* of interfaces, but I 
don't see anything about state associated with the interface itself 
for static functions to read/modify.
