Agreed.

Well, the registry is supposed say whether the label should be seen as 
obsolete, of limited use or 'normal'. These judgements are not simply a 
question of 'you have label and you have bytes, this is how you get 
characters'. The reasons why products *may* need to have some kind of 
support for 'unicode' and 'unicodeFFFE' are the same as why they 
probably should be considered 'obsolete' or 'of limited use': They 
interfere in a negative way on the stability of 'utf-16', 'utf-16le' 
and 'utf-16be'. And these negativities need to be reflected somewhere. 
It also, in order to try to get a picture of those issues that I have 
focused on what happens if so and so.

Meanwhile, perhaps my new version of the 'unicode' registration looks 
better?
