HLASM warns about them when not using GOFF because without GOFF it cannot produce the data needed by the binder and loader to resolve them. In my opinion, it is unlikely that there will ever be a way to do relative addressing between an RMODE 24 or RMODE 31 segment and an RMODE 64 segment because in general that would require an operand size of 8 bytes (and a resulting instruction length of at least 10 bytes).
