What are the use cases for adding/removing images? It seems to me that 
they would be better addressed by having a good API for interacting with 
srcset rather than adopting an element based design. For example one 
could have HTMLImageElement.addSrc(url, options) where options is a 
dictionary allowing you to set the various srcset options.
