I agree it's pretty weird, but I can't immediately see any reason that
it shouldn't (be allowed to) work. It would only get interesting if
you want to posit that ISO years shouldn't be based on the Gregorian
calendar that far back.
Some experimentation shows that it doesn't work, or at least doesn't
give sane results, in pre-8.4 branches; I have not traced the code to
make sure but I think this is because of the other bug I noted with
passing the wrong year variable to the isoweek code. I don't think
that's important enough to back-patch but it is worth getting it right
going forward.
