Thank you for the example. You are right, gnus-start.el is using
locate-library to check existence of its init files and uses load to search
for them again right after. Given how that code is written, we probably
should keep locate-library as is since at least some people people are
relying on its ability to locate arbitrary files that are not libraries.
