The major difference for ArmV8 is the 64 bit address space, but the chips are 100% compatible with v7 and before.  The only potential benefit of v8 for Pd would be the NEON instructions which are 128 bit wide vs 64 on v7.  Of course someone would have to write that NEON code first...

just earlier today I wanted to install timbreID on a raspberry through
deken. It was hidden by default because the binary is for armv7 so
considered a "foreign architecture" because the Raspberry 3 is armv8. I
installed the armv7 and it seemed to be working.
