I got burned many times when losing hard drives or computers, upgrading computers, switching between computers or just using different browsers, that bookmarks tied to the browser are ephemeral and shouldn't be trusted.
I effectively solve this by creating custom websites to service those needs. RSS was invented for some of those purposes and still exists today. "SaaS productivity" is out of scope for a bookmark and I wouldn't trust a browser extension.
You want a UX that's tailor crafted to your workflow? Build one. Or find a service/FOSS project that has one built for you. I'm not sure expecting a basic feature of "save this website URL in a CSV file" should be elevated to anything more.
It looks like this is a Chrome only service, so when my chromium installation gets janked and I have to switch to Firefox, then my bookmarks are lost again.
It also looks like this is a Google service which means if Google sunsets this service, which is not unlikely considering their history, then my bookmarks are lost.
It looks like it's also tied to my Gmail account which means if I don't have a Google account, have multiple Google accounts that I want to keep separated or lose access to my account Google account, my bookmarks are lost.
All the above scenarios, with some degree of generality, have happened to me before in one form or another.
