I like your POC.

This feature seems stalled, is this issue the only thing blocking it?

You could use a Unicode character (RIGHT ARROW → for instance), it's
unlikely to occur in a normal search and replace, and could be specially
encoded to "→→" in those cases. So you'd store "X→→Y→A→→→→B" to record
FROM="X→Y" and TO="A→→B".  It's an unambiguous encoding.  If that's too
hacky, let's find another way, and let me know how I can help.

Thanks!
