I've consulted with several engineers and support folk. "Ephemeral" is a commonly used term in our community. 

Writing for ESL readers is a project unto itself. If we want to re-write all of our documentation for ESL readers, we need to do that programmatically, not just by randomly changing vocabulary. I have not heard from anyone that this is a goal for our docs. 
The best way to create good docs for non-English speakers, IMHO, is to internationalize the docs with good, human-created translations rather than dumbing down the English docs to some kind of simplified form. I have never seen this approach work well. I have often seen this approach create very terrible documentation.
