Using #$foo could be problematic when using package inheritance, as
explained by Ludo in the recent blog article.

This leaves us with #$(this-package-input foo) and "search-input-file"
as alternatives. Maybe we should promote the first one, but I see that
you have rightfully started a thread about that.

Thanks,
