Now regardless of what you think about summary, the two are not the same.

To merge summary into caption is to eliminate summary and redefine
caption. User agents do handle the two differently. For instance,
summary isn't printed out to the page; caption is.

So not only is this path causing confusion as to how to use summary,
it's also redefining one of the older HTML elements.

It really is a sloppy approach.
