Not who you're talking to, but there is none. Browsers have had "Bookmark all tabs" functionality for ages, which completely replaces tab hoarding. Especially now that the content of the page you visited 5 months ago isn't actually loaded in memory. It's basically a bookmark, switch to the tab and the content is reloaded.
Yes, I am aware of bookmarks, and as someone who used to use them quite a lot, I'm aware of their limitations. Some things are just ephemeral and should remain so. Browser search is great. As you mentioned, tabs lazy load so the main functionality is the same, so it's presumptuous to assume I get no value out of my organizational strategy.
