RFC: Split Source vs Build levels

[Mark Lodato]

Hi all,

As discussed in Monday's meeting, I wrote up a brief proposal to split the ladder into independent "Build" and "Source" levels. Please take a look at the Separate “build” levels vs “source” levels section here:

Any feedback would be appreciated, preferably as Docs comments. Also let me know if there are more details to add to help us make the decision.

Personally I'm on the fence.

Best,

Mark
