I really think it is.

Having alternative ways to represent these doesn't invalidate or affect 
my argument.

I would not say I aspire to the view you quote.

If you encode a certain shape, it may get used for a range of text 
elements. This would (de facto) encode these text elements via that 
shape. If it is later felt that the given shape should not be used for 
the full range of text elements, then you could say that the "implicit" 
unification based on the usage (or, if you will, "fallback usage") was 
mistaken and should be better handled by two (or more) shapes. This 
represents a "de-facto" disunification.

However, where I part from your description is the "everything is 
already encoded". That would not be the case anywhere a range of text 
elements cannot be represented at all. Your statement also implies a 
"correctly encoded" or "successfully encoded" which is different from 
"there's an encoding that some people use as a fallback", which, if 
disunification should prove proper later on, would be a better way of 
describing what was the original situation.

Perhaps the point is subtle, but it is important.

In the current case, you have the opposite, to wit, the text elements 
are unchanged, but you would like to add alternate code elements to 
represent what are, ultimately, the same text elements. That's not 
disunification, but dual encoding.
