bogus sde behavior of 64-bit executables

Imo on emulated platforms not supporting 64-bit mode 64-bit executables should either not be permitted to get loaded at all, or should assume basic 64-bit functionality. However, with -p4 I get

TID 0 SDE-ERROR: Executed instruction not valid for specified chip (PENTIUM4): 0x7f0f47e3df23: movsxd rdx, dword ptr [r8+rdx*4]
Image: /lib64/ld-linux-x86-64.so.2+0x1f23 (in multi-region image, region# 0)
Function: _dl_start
Instruction bytes are: 49 63 14 90

and with -quark I get

TID 0 SDE-ERROR: Executed instruction not valid for specified chip (PENTIUM): 0x7f2c5a4e5e55: cmovz rcx, r8
Image: /lib64/ld-linux-x86-64.so.2+0x1e55 (in multi-region image, region# 0)
Function: _dl_start
Instruction bytes are: 49 0f 44 c8
