As someone said already, in todays algorithm, we block things based on
blocks, not scripts. If people want the selection on scripts back,
fine, but that is something I want consensus on (as well).

I though I explained and that I had not heard back from you :-)
Reason is that applications that block those codepoints will not let
the codepoints be resolved. So starting using those codepoints will
This was exactly why we had MAYBE NOT category.
And the reason why we have the backward compatibility category (so
that the algorithm can be kept in sync with the Unicode data).
That said (which we said in earlier discussions) every time RFCs are
updated a decision has to be made regarding the change, and the reason
why etc etc.
