What do you mean here WRT "not sure why the PAE is even offered" ?

Because PAE is irrellavent in 64bit long mode. PAE only provides
pointers for 36bit memory addressing. x64 chips have 40+ bit memory
addressing and 64bit pointers and registers.

So, why is there a seperate PAE kernel when it's not needed?

There isn't a kernel-pae for x86_64.
