Well, the status of `ß' is indeed complicated, and the radical
solution used in Switzerland has certainly benefits.

I don't see much difference to the English example of `re-cord'
vs. `rec-ord'. And Swiss people won't start to use `ẞ' just for
getting the right meaning...

Yes, and it was never successful. The introduction of `ẞ' into
Unicode a few years ago was mainly driven by experts, not something
that had big popularity before.

Yes, let's see how everything will evolve. Regardless of that,
software should support the status quo as good as possible.
