To the extend where they can be used on their own, yes.

I haven't looked at this recently, but historically, cua-mode started
out by doing region-based copy/paste and at some point I extended it
do do rectangle-based copy/paste as well, with basically the same key
bindings, except that you start a region with C-SPC and a rectangle
with C-RET.

Then later again, I added the global mark feature, C-S-SPC, which
integrates fully with cua's region/rectangle copy/paste features.

So it started simple, and grew more complex.

Later, I tried to separate as much as possible of the rectangle
and global mark stuff into separate files cua-rect.el and cua-gmrk.el
but there still are some links between then and the basic cua.el which
I can't easily get rid of -- so I left it at that point, and haven't
had time to go further.

If you can see any way to make a cleaner split, you are most welcome
to make suggestions (but please be specific -- many people tell me
I should do this, but they never suggest how it can be done).

In _my_ context the cua-rect functions are only used when you
have enabled cua-mode and after you have hit C-RET.  

cua-rect is auto-loaded the first time you hit C-RET, and after that
everything you need is available...

If you want to use the cua-rect stuff in some _other_ context, you
could require cua-rect explicitly, but doing that would be at the risk
of breakage if I decide to change stuff in cua-rect unless I'm aware
that something else is relying on parts of it in specific ways.
