@fredlf I'm glad you know some engineers and support folk who are linguistic experts.
Let's ignore what statistics say and go with some engineers' decision on this then and keep this uber complex paragraph.

PS // BTW - Writing for ESL readers is not a project unto itself. It is year 2014.
The new trend tends to be more like even with enough budget and the staff to create docs in 4 languages and support docs in an additional 10, writing your main docs in English in a way that can be understood easily by ESL readers without making it too simple.

And this is what was targeted and partially done with the initial resurge of the [Docker] docs v2 and its certain sections.

 - Although the best way would be to write the docs in 99 other languages, it is not a realistic possibility at this stage. 
 - Statistically, "Ephemeral" is not a commonly used term (given the scenario above) and as I explained, this paragraph will need to be *deciphered* by a big huge humongous amount of docs readers due to its unnecessary complexity.
 - I don't think this paragraph should be kept as is.
