They don't need to start it to get the metadata. All that's sent is the content-disposition header with the suggested file name.

That is the start, unless you perform a HEAD followed by a GET (which takes 2 round-trips instead of one and may not even be correctly supported). And because any link can lead to that, every single link you click would have to be implemented via 2 round-trips, that's complete madness.

Nonsense, there is no situation in which "all that's sent is the content-disposition header", that header is part of a full header section and immediately precedes the content itself.
