AFAIU, Hindi is one language that uses the Devanagari script.  Is this
correct?  If that is correct, how about having two lines in HELLO: one
that says "Hindi" and shows a Hindi greeting, and another that says
"Devanagari" and shows a greeting in some other language that uses
Devanagari?

In Emacs, 11 years is nowhere near "long enough".

And anyway, the script will not be renamed, since we follow Unicode in
script names.  The patch didn't rename the script, and rightfully so.

As I wrote in the review of the patch, we cannot suddenly remove input
methods that we had for 20 years.  We must find a less drastic
solution.
