Yes, that is the concern expressed in my initial paragraph which you
didn't quote. So this is a concern for developers of browsers and
tools that can be used to download resources from the web.

The concern the i'm trying to express in the paragraph that you are
quoting above is this:

1. User navigate to a website with a <video forbidsaving src="myvideo.ogv">.
2. User tries to save but notices that there is no "save video" menu option.
3. User instead clicks "view video" menu item.
4. This navigates the browser directly to myvideo.ogv. I.e. not to a HTML file.
5. User can now use the "save video" menu option since there is no
HTML tags containing a 'forbidsaving' attribute.

So this is a concern for content producers that want to take advantage
of the proposed attribute.
