PG described a process by which the most literal-minded participants -- those with abnormally low tolerance for ambiguity -- drag everyone down to their level. I would welcome measures that neutralize that process even if the negative consequence you describe comes to pass.

Why is "100% clear communication" an assumed universal good? Some jokes are only funny because some people don't get them. And yet, this--as I might term it--"populist heartburn" at realizing one is in the not-getting-it majority, and demanding an explanation, ruins the fun of those who do.

Bob Dylan's "Ballad of a Thin Man" might be appropriate reading here. :)
