I suggest making this standard feature a little more
explicit in the emacs manual.  I think it's only mentioned
in the Minibuffer History node (in Emacs 27) which is fine,
but the only index entry for this is "future history for
file names".  I think it would be better to also (or just)
index "future history" in the previous paragraph.

Also a sentence explaining how this standard feature
commonly behaves would help.  Something like:

This is often a value at point relevant to the command such
as a symbol, word, file name or color.

(with perhaps a mention of thing-at-point)
