That is the situation as I understand it, yes. I too have an ARMv4
data book at home that I purchased from a book shop without entering
into any kind of restrictive agreement.
I think the real question is how useful ARM support will be if we
can only support relatively old instruction sets.

I think the answer to that is yes:
dellow [~/src/valgrind-3] % ls -d VEX/*/*arm*
VEX/orig_arm/nanoarm VEX/priv/guest-arm/ VEX/pub/libvex_guest_arm.h
VEX/orig_arm/nanoarm.orig VEX/priv/host-arm/
