I see it very differently. I've just learned over the years with iOS system and Safari random restarts and occasional crashes that bad stuff happens and you can't depend on tabs open. Bookmarks are at least a stable record. You can also backup via your computer or iCloud them for safety if it's really important.
Honestly if you made it 10 years without anything bad happening, you're very lucky. I remember there was one iOS version at the tail end of the 3G lifecycle (the second released iPhone) where the phone would randomly shut down for no reason. Once you go through that, you don't leave things to chance.
