Yes. From PoOps: In the z/Architecture architectural mode, a restart interruption causes the old PSW to be stored at real locations 288-303 and a new PSW, designating the start of the program to be executed, to be fetched from real locations 416-431. In the ESA/390-compat- ibility mode, a restart interruption causes the short- format old PSW to be stored at real locations 8-15 and a short-format new PSW to be fetched from real locations 0-7. The instruction-length code and inter- ruption code are not stored.

Maybe it is no longer used.

Hardly a circumvention. if the storage at location x'00000004' is zeroed out.
