That's correct.  `require' loads the entire library/file.
If the load doesn't raise an error then everything in
the file is loaded.  If it does raise an error then
nothing in the file is loaded.

The granularity of a feature (or a subfeature) is a file,
nothing smaller, because the granularity of loading is a
file, nothing smaller. (Loading can load multiple files,
of course.)

Read the doc I pointed you to, if you haven't already.
The first sentence tells you that "`provide' and
`require' are for loading files".
