Yes.

Yes.  I think that will be the simplest to use.  Please be
sure that empty library lists in cases like

 tll(tgt PRIVATE a PUBLIC INTERFACE c)

work because they could come from

 tll(tgt PRIVATE a PUBLIC ${list_of_libs_maybe_empty} INTERFACE c)

We considered such cases way back when first discussing that interface.
The use case is that there is an ordered implementation dependency on
"a;b;c" but only "b" should be in the link interface.
