I utterly detest timespec.. it makes no sense what so ever.

Can't we just, for new syscalls, simply use a s64 nsec argument and call
it a day?

This would stop working in the year 2262. Not a good idea.

Make it u64 and it stops in 2552, i.e. 584 years from now which is
plenty. Lot's of the kernel internal timekeeping will stop working at
that point, so that interface is the least of my worries. And TBH, my
worries about the Y2552 problem are extremly close to zero.

What do we win by using u64 instead of timespec?

Or what's so bad about timespec?
