I just mass-bookmark mine into a new bookmark folder periodically. Keeps it from getting anywhere near 2k.
I've been doing this for years and have never, not once, looked at the bookmarks. But it gives me the peace of mind I need to close all tabs and start over.

Exactly. You can even name the bookmark folder either with the thing you're researching/interacting with or just by the date if it's a ton of miscellaneous stuff. Then later on you can go thru and delete all the date-named bookmarks older than 6 months. At that point just search your browser history
