The above list is the same as I get on my system, so far so good.
E.g. if I press Ctrl-Shift-5 I get the same as you, keycode 37 and
state 21, cleaned 5.
The difference is that if I press Ctrl-Shift-u before and then pressing
5 while holding Ctrl-Shift I still get keycode 37 but it is inserted as
5 as part of the Unicode string.
So, apart from the triggering of other keybindings, this is what I'd
expect.
Can you confirm this behaviour so far?

Yeah, I don't see this as any alternative, not even a workaround.
