Good idea: autocomplete Assets. Also autocomplete Articles comes in my mind.

Currently the main difference between the autocomplete helpers are the
delimiter and [1]. Maybe for 4.4 we can use the same delimiter on all
autocompletes. Is there a reason for the different delimiters?
If we have to stay with different delimiters we can use a new
data-autocomplete-delimiter to tell autocomplete.js which delimiter to
pass to the helper.
I'm currently not sure how to handle [1] if we don't want to hardcode
"what" in autocomplete.js. The idea was exactly what you described
above, which would help to write custom ticket autocomplete helpers.

I would simply replace here [2] "cssClassMap[what]" by
"what.toLowerCase()" to remove hardcoding what and still adding the same
class if someone use this.

Next I have time (probably after my vacation) I will create a
PullRequest for this.
