Further thoughts -
With the presets issue, I strongly suspect that this is an example of how you just can't win if you are a software developer (like being part of the Adobe LR Team, perhaps). With best motives in the world, they think - "Gosh, let's give the users a whole raft of brilliant new develop presets!" And they do. Then mingy old gits like me look at them and think, holy cow, these are all truly horrible and I will continue to use my own presets thank you very much indeed.
The solution, I think, is to just make this more user-configurable. The factory presets should be capable of installation or removal, just like any other plugin. The we can all be happy.
