And which generally is. At least, I'm pretty sure most people arent
running less swap than physical ram. Isnt the general rule of thumb these
days that swap should be at least 2x ram?

A bit beyond my kernel hacking abilities unfortunately. But even good
things (GGI, etc) may require a _lot_ of public pressure to get included
due to severe biases by developers.

The question isnt whether its do-or-die. Eg we can live without GGI, but
its a very good thing to have in the long run. The question is whether its
fundamentally useful.

For instance, one could advocate that strace is enough to track down bugs
in user applications. But some problems really require core dumps and gdb.
