We could indeed add a new feature in this way. However, we're trying to 
limit the number of redundant features we add, because each such feature 
increases the complexity of the platform overall.

These are not the same.

These are really not the same.

These are again veeeeery different.

These are close to the same, and they're not alone in being rather 
redundant -- <th>, <h1>, <label>, etc. (This is why I'd really rather not 
have to introduce another <legend>, despite the problems with <figure>.) 
This is something we're trying to avoid.

You still can't omit the </script>, though. That's what I meant.
