I love this concept. Work on a rewrite and then fold lessons learned methodically into the existing, stable, proven one.

> SQLite4 was an experimental rewrite of SQLite that was active from 2012 through 2014. All development work on SQLite4 has ended. Lessons learned from SQLite4 have been folded into the main SQLite3 product. SQLite4 was never released. There are no plans to revive it. You should be using SQLite3.

Remember when Win95 could be crashed or even rooted just by pinging it the right way? We really have come a long way.

I also remember SMB vulnerabilities that stayed unpatched for years on some machines. That was already when Metasploit existed, so you could inject VNC into most Windows hosts on local network with just a few commands. These days at least the patching is super fast.
