It would be a good idea to document that this is a workaround.

I think we shouldn't try to check satisfaction even for instantiation dependent 
arguments, because substitution for these can still fail later.

Do we have a test case for this? It would be good to have this, with a FIXME 
explaining.

For example, forming a reference to void on a template argument for a template 
type alias, where the corresponding template parameter is unused.
