Even as a local convention, it is helpful to have a document that describes it.

Only the recipient's environment needs to know.  I certainly don't 
need to know if I'm sending you email if the particular address I 
have for you is subaddressed.

At present, the document does contain text about list servers 
recognizing subaddressing.  This is the one area where I'm not 
convinced.  I can see the benefit, but I think that once we allow for 
anything that isn't after final delivery knowing about subaddressing, 
at that point we have changed it from a purely local convention to 
one that does indeed have meaning elsewhere, and we pretty much are 
then forced to choose a single (or maybe two) character for the 
delimiter.  Because of this, I am wavering as to if we should mention 
list servers or not.
