the idea is to use 'find' if you want something fancy

I don't get it, can someone explain? It also appears in the ML thread linked elsewhere, and I don't understand it there either. (I understand the reasons for the change in behaviour, just not this specific line.)

find is essentially the command line tool for traversing the file system hierarchy recursively. It's got a million options, e.g. whether to follow symlinks, depth, file/directory/device/.., user, group, change time and many more. When you use grep -r, it only does the most common thing which is to just go over all the files. If you want something more "fancy", you can use find, e.g.:

  $ find -name '*.c' -type f -exec grep printf '{}' +
