I can confirm that this also works perfectly well for browser bookmarks!
That's what you think until eventually you have 5k+ browser tabs open at once and your browser has slowed to a crawl so you need to dump them all into bookmarks or a session backup and start the cycle again
Tridactyl also gets unusable.
I finally cleared all the tabs out last week and started over, because it was clear my "reading list" was simply never getting read, ever. There were tabs from February still in there, never read.
