I think there's a PR for this.

Actually this is the old C `struct hack' idiom.  In traditional C you
were allowed to declare the last field in a struct as an array; then
you could allocate additional space and it would act like a
variable-sized array, without the overhead of an additional pointer in
the struct.

It isn't very common, but it isn't uncommon either.
