I think I might be missing many opportunities for target finders, target collectors and exporters. Let's list some here in this issue:

Target finders

• in eww buffers, the link at point could be targeted as a url.

Target collectors

• in eww buffers, all the links could be collected as urls. Or a new type weblink could be introduced which has both a url and a title.

Enhancements to existing collectors:

• the collect collector, when the region is active could collect only the candidates in the region
• the dired collector could collect only the marked files
• similarly, the ibuffer collector could collect only the marked buffers

Exporters

• bookmark should export to bookmark-bmenu-mode. Done.
• line should export to occur-mode. line was renamed consult-location and it does export to occur mode now!
• url or weblink if introduced could export to eww-bookmark-mode, which seems like a reasonable mode for a list of links even if they are not actually bookmarks. (I'm not sure about this.)

Actions

• url could use a download action (I'm thinking I'd only use this outside of eww buffers).
• kill-ring could use a "remove from kill-ring" action.
