To be fair... Lots of people just never close their tabs. So there's very real resource limitations. I've seen my partner's phone with a few hundred tabs open.

I would like this feature if I had more control over it. The worst part is when clicking a tab that was unloaded which makes a new (fresh) web request when I don't want it to

In firefox it's possible to disable it: https://firefox-source-docs.mozilla.org/browser/tabunloader/ . Enabled is probably the reasonable default for it though.

Particularly if you have maybe 40 tabs open and 128GB of ram.
