Comment (by peterwilsoncc):

 I've found WPdirectory does a slightly better job of finding code,
 searching `extends [A-Za-z_]*Walker` returns the following:

 * Themes: [https://wpdirectory.net/search/01DFVS3VNYJJR948DPTT9APEC1 1496
 matches]
 * Plugins: [https://wpdirectory.net/search/01DFVS7CTWSBHN2SYKF5F3BMR9 1127
 matches]

 As custom walkers are more common in themes, I'm concerned about breaking
 BC as themes are less likely to be open-source than plugins. Most sites
 run a custom theme.

 Custom walkers are required for relatively common features, for example
 adding data attributes and IDs to `Walker_Nav_Menu > ul` for use with
 generic JavaScript libraries.
