starbright I ran EOL 3 until the 7 came out, so I do get where you're coming from. I loved that tiny little thing.
But it isn't about max safety (or I wouldn't still be using a 7). It's about whether the device exceeds the minimum threshold for being considered for inclusion in the "safe" category. Just as my 3 wasn't, your 5 isn't.
Unfortunately, support for non Google/Apple devices is so terrible that, by comparison, an EOL 5 might seem great. But it still doesn't pass the minimum bar.
I feel for you, I do, and hope we see you around with a 10.
