 Replying to [comment:61 johnjamesjacoby]:
 > Consider also that using `like_escape()` did not previously require a
 touch to the `$wpdb` global that's now required using the new
 `$wpdb->esc_like()` method. Is there any objection to a general
 `esc_like_sql()` function that does the global touch for us, and making
 `like_escape()` a wrapper for it?

 Using esc_like() without a database is a rare situation that would not be
 encountered by novice programmers.  There's nothing wrong with adding
 another function, but it's unnecessary.

 Regarding deprecation: Seems like a lot of fuss over a one-line function.
 It won't be used in core anymore, and however that's signaled is great.
