Looking into it further, it seems you are correct. It was assigned out
of the 0/16 reserved block, but at least as far back as December, 1995
[RFC1884] the IPv4 mapped addresses existed. Since I-Ds are not
archived, I have no idea when they came to be; I'd guess pretty early
on.
I guess where I got the idea that they'd be bogons is that they are not
part of the currently allocated, normal address space. Sorry about that.
