Illustrator creates bloated and messed up SVG code. Please Adobe, make Illustrator so it Exports much cleaner and simpler code.

I'm working with a team of developers and they mock the SVGs I'm giving them. They won't even use many of them, because every single KB matters, and when an SVG file goes from 10KB to 50kb to 100KB, it makes a really REALLY big difference when including in an application or website, so much so, that the developers refuse to use some of my SVGs!

I've attached a script generated SVG (Clean) and the same exact file after being opened and saved within Illustrator. The code from 51KB -to- 65KB. That's enough to fail ...and look at that code! The Illustrator exported (Save As...) SVG is a mess! Illustrator completely ruins the arcs and circles!
