Why and how does aarch64 cpu wheel keep rpath instead of runpath?

As no disable-new-dtags and patchelf command are found in the repo, how does aarch64 cpu wheel of keep rpath instead of runpath in default? Will the RPATH cause problem (as use of DT_RPATH is deprecated)?

in nightly whl (20250417)
0x000000000000000f (RPATH) Library rpath: [$ORIGIN/lib:$ORIGIN/../torch.libs]

build by source code
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/lib]

It seems that RUNPATH is replaced by RPATH when auditwheel is adding $ORIGIN/../torch.libs to whl.
