That seems unduly harsh.  None of us are perfect; we all make mistakes.  
The lowercase part of Cyrillic casing pairs do resemble small caps for 
most letters.  One casual mistake given in an aside does not negate the 
rest of Marcel Schneider's points.  One error about a related script 
(Cyrillic) does not undermine his thoughtful expectations for the Latin 
script as a French language member of the Latin script user community.

As an aside, calling a mister a doctor isn't insulting but calling a 
doctor a mister might be.  I suppose we could all call each other 
magister here, just to be safe, but we can't seem to agree on how to 
encode its abbreviation.
