And which we specifically prohibited in RFC4120.
Everyone does it because it's what the implementations have always done, 
and making the transition is hard -- especially when some widely-deployed 
implementations still use the old behavior by default.

I will note that I have written multiple implementations which avoided 
krb_get_phost or krb5_sname_to_principal specifically for this reason.  It 
has never made me happy.
