It's mostly just how to make it intuitive. There are so many options, and orientating them so they work reliably and understandably for the driver isn't always an easy task, depending on the driver, game/strategy, etc. I know for us, we haven't done much with true 3DOF control (my oversight, Ether), but there are still a lot of variables to play with.

I'm not sure though and I could be wrong, I'm not very experienced with the programming/control of swerve drives.

We've used fixed-speed spins on our swerve for 2 years. It's worked quite well for us, but our driver only really uses them in specific cases (aiming in Breakaway and turning the heck around in LogoMotion), with crab and snake covering most of the direction changing. I know a few other swerve teams do it this way, but others may well have variable speeds. Lots of options.

I'd estimate an extra 10-15 lbs for a swerve drive. Then again, I've never really even seen one

Our
modules are 9.1lb each.
