FWIW, I do not think this is a good idea.

Emacs is the only application I know which has a unified way to interact 
with history of past actions and suggestions for future actions.  The name 
"future history" is not only cute, it is also an excellent one, from a 
mnemonical viewpoint, to remember that the M-n is the key binding that 
should be used to access those suggestions.  What I would suggest instead 
is to add an explanation between parentheses that "future history" is what 
is called in some other applications "suggestions" (and possibly update 
the glossary accordingly).

The idea of replacing DEFAULT with (DEFAULT . SUGGESTIONS) is also not 
really optimal IMO.  The problem is that DEFAULT would not only be the 
value that is used when the user hits RET with an empty input, it is also 
the first value inserted when hitting M-n, that is, it is also the first 
SUGGESTION.  What I would suggest instead is to replace DEFAULTS with 
FUTURE-HISTORY, with an explanation that the first element of 
FUTURE-HISTORY is used when the user hist RET with an empty input.
