It seems worth resolving the Unicode Security Considerations question relative to the observation in https://github.com/whatwg/encoding/issues/115#issuecomment-312645847.  I wonder if @srl295 or @kenlunde could help us with that.

To restate, why is an escape followed by an escape considered problematic, whereas going from ASCII to ASCII, or uselessly going between ASCII and Roman, is not considered problematic?

Also taking into account that an escape followed by an escape is typical in email as per https://bugzilla.mozilla.org/show_bug.cgi?id=1374149#c5.
