It probably is too complicated a goal to handle changes "from any direction" "at any time" during layout.

Easier will be to make tools that help "passes" of directed activity succeed.

As in:
1. schematic prelim, 2. place components, 3. Do some layout of non-autorouted power traces,
4. Notice some things you forgot and add them to schematic. 5. forward annotate pass, perhaps helped by a make file,
and/or a makefile and a launcher button for it.  6. Do some layout fixing up the forward annotated footprints,
7. autoroute 8.  add some attributes to pcb elements(not even supported yet)  8.5 back annotate pass.
9. Do some .sch fixing up, add more forgotten attribs, etc. 10. forward annotate pass, 11. repeat while necessary.
