Sure we do. Who is going to find all the flags? I found PF_KTHREAD. :^)

More seriously,

/proc/$pid/stat was expanded to include tsk->flags in 0.99.1 (!!!)

Developers kept adding and shuffling flags probably not even realising
what's going on. The last incident happened at 5.10 when PF_IO_WORKER
was exchanged with PF_VCPU for smaller codegen.

Can I get PF_KTHREAD wasrning because it is _definitely_ used?

I'll post CSV file from 2.6.11 days:
