Just for the sake of the archives, turns out that on the lenovo T430 and T530
you should ignore the Lenovo documentation I quoted above, and you can
indeed use the PrtSc key between Right Alt and Right Ctrl, that key works
just fine for Sysrq.
I have no idea why Lenovo felt they had to document some complicated
alternate software sysrq with Fn+S
Anyway, hope this helps someone.

Well... I feel resposible for sysrq stuff... I wanted it to be
non-intrusive. But it might have been bad choice - sysrq was not meant
to be used as a shift.
Sometimes it works, sometimes it does not. Don't blame lenovo for
that.
Maybe it should be modified to take sysrq and _then_ key?
Or maybe we should use something like lshift+rshift+lalt+ralt+key?

It can't hurt to add alternatives like the one you suggested. They don't
have to be convenient, although the one you suggest takes 5 fingers at
the same time :)
Is there anything that uses
shift+ctrl+alt + key
in userspace?
I checked enlightenment 17, they have crazy key bindings, but nothing
that uses all 3 modifier keys at the same time.
If that's not safe, feel free to add one or 2 more just to be safe.
Thanks for suggesting this.

I vote for "something like". Some keyboards (such as my Thinkpad X230
with UK layout) have lshift, lalt, rshift, but no ralt. the ralt is
replaced by AltGr.
