New setting: Open large files without syntax highlighting

As was noted in one of the posts in the forum, the slowness of Sublime Text when working with moderately large files (e.g. 20 MB) comes from the syntax highlighting. Without it the editor is fairly quick.

Could a new setting be introduced that would make the editor open files larger than X kB/MB (where "X" is a number chosen by the user) without syntax highlighting? (if needed the user can set the syntax later after opening the file)
