I don't have a problem with that. I'm just saying that it DOES make 
(more) sense to use the envelope extension the way he is doing.  :)

Did you encounter any problems with the envelope extension in your own 
experience?

Well, using ':matches" for one key value without wildcards is a bit 
useless. In that case it is equivalent to ':is' or leaving the match 
type out. But yes, I agree, if it is part of a large list of match keys 
(only some of which have no wild cards), it does make sense.
