It is disturbing that our co-chair of LTRU WG still completely
misunderstands the purpose and usage of Suppress-Script.

For the long-term future, when tagging documents, Suppress-Script
MUST continue to be honored, in order to ensure compatibility
with application software (e.g., word processors) and embedded 
software (e.g., firmware in network printers).

No network printer now in existence currently supports 'script'
subtags.  If you send a document (e.g., PostScript) to a network
printer with an external language tag of 'en-Latn-US' (e.g., in 
the IPP 'document-natural-language' attribute), you're going to be 
sadly surprised to have it rejected entirely or else rendered per 
that printer's default natural language (e.g., 'ru', Russian), 
that is to say with some very odd-looking glyphs.

"Tag wisely" means don't include redundant information.  This
applies to script subtags just like all other subtags.
