Hi Vint,
I obviously missed the conflagration. I will go back and check
archives to see if i can find the signs and reasons for it.
In the meantime, I am not trying to burn anything, just trying to
understand the reason for such decisions. Are they technical?
policy? something else altogether? Is it the single script per label
rule? A homograph problem?
If this isn't the right place-time to ask such questions, where and
when is? If making the answer public is too risky, can someone give
me the right clue privately (though I don't know why we should ever
be afraid to talk of the reasons for things in public). Is the
reason perhaps documented in some i-d/rfc somewhere? I think it
certainly should be if the question is so dangerous.
Just looking for a clue on why the strict prohibition/avoidance. I
got to the question in a quest to look for answers for non literate
users - an extension of the ML problem and if there is a technical
answer i would like to know.
thanks.
a.
