We've not supported loading individual modules from the 'kernel' bundle
for some years. Thus trying to do




first has raised an error for quite a while now (I think from around the
time we rearranged from "l3in2e"/"xpackages" to
"l3kernel"/"l3packages"/"l3experimental": if you really want to know
I'll check back over the SVN).

As part of making expl3 loadable on top of formats other than LaTeX2e
(at least, on top of plain/ConTeXt: others not tested), it was much more
straight forward to roll all of the l3kernel code up into a single
extracted files. That makes no difference to how things are loaded it
should be more-or-less no issue: you used to need
"\RequirePackage{expl3}" and you still do. This also has the advantage
of reducing the 'log noise' from loading expl3 and the risk of
mis-matching files for the kernel part of the bundle.

Note that this change was included in the usual announcements I make
before uploading code to CTAN.
