It is not _my_ implementation.  What is mine is the addressing 
architecture that uses fe80:1::1.

The implementation is linux.  Linux is in widespread use.  Anybody with 
linux can type ifconfig eth0 add fe80:1::1.

I think that command is not a violation of standards.

The only thing that may contradict someone's mind when typing that 
command is the 54 0 bits in RFC4291 (because ifconfig says '1' instead 
of 0).

I wonder whether this answers your invitation to share.

(and I do not know what is an 'outlier').
