Yes - migration v2 didn't add the page compression support.
I should have included this in the "Areas for improvement" in the
feature document.
xc_offline_page has nothing to do with migration, although it used to
share some infrastructure, which I suspect is why the two are linked.
xen-hptool (which I keep on mistaking for a brand of hardware vendor) is
a command line utility which uses some of xc_offline_page.c
