That doesn't help with B accesses on L platforms and vice versa.
Having an optional boolean parameter (gating reverseBytes) will help.

Also, it makes Unsafe non-final, which frankly gives me the willies.
(Technical term, used by folks that have been through too many security escalations.)
Let's not create any new ways for industrious hackers to attack Unsafe.
