see clsguide.pdf (in the LaTeX base-doc)::
LaTEX has three types of command.
There are the author commands, such as \section, \emph and \times: most
of these have short names, all in lower case.
There are also the class and package writer commands: most of these
have long mixed-case names such as the following.
\InputIfFileExists \RequirePackage \PassOptionsToClass
Finally, there are the internal commands used in the LaTEX
implementation, such as \...@tempcnta, \...@ifnextchar and \...@eha: most of
these commands contain @ in their name, which means they cannot be used
in documents, only in class and package files.

no need, but the convention is to use \RequirePackage in a package or
class and \usepackage in a document.
