That's right. \RequirePackage and \usepackage maintain internally a
list of already loaded packages. There is one potential problem, you
are not specified a different list of options. Thus if you use
\RequirePackage{something} without any options, it is harmless. If a
user needs "something" with some options, he or she must load it
explicitely with these options in advance.
