No, that's fine.  As its doc string says, `provide' just "[a]nnounce[s]
that FEATURE is a feature of the current Emacs."  So there's no
requirement that FEATURE be the name of an existing file.  But `require'
loads a feature from an existing file, so it has to find that file,
using the name of the feature as a default.  But if the file providing
that feature has a different name, you have to pass that name (just the
base name without extension) to `require'.
