It really has been. The code is no longer checks the size of a block, but the 
weight of it. For all intents and purposes the block size limits has been 
replaced in favor of a block weight limit. It's just been designed such that 
the new rule is more restrictive than the one it replaces.

Now, I'm not doubting you can argue the semantics on the difference between 
"replacing with a more restrictive rule" and "leaving the existing rules, but 
adding a new one" -- but it's uninteresting and only serves to confuse novice's 
like CANNON into thinking that there are two rules/spaces/limits for 
transactions.
