I do not believe there are any context or grob properties that accept 
ly:context-mod?.  But who knows what the future might hold.

It could be reasonable that the "\override Foo \with { ... }" pattern 
implies the nested use of \with, meaning you could not assign a context 
mod in that syntax.  You would have to revert to the existing "\override 
Foo = \with { ... }" form.

But it seems a shame that \tweak does not get the enjoy the same 
benefits.  I guess you would have to simply decide that \tweak always 
assumes ly:context-mod? is a smart alist modifier.
