I agree.  I know the original RFC didn't get many responses but perhaps discussion will pick up given that patches now exist.  The discussion should happen on both cfe-dev and llvm-dev because it affects both.

In particular I'd like to understand the motivation for this.  Is it for experimental purposes, to aid in compiler tuning, to allow the user to override compiler decisions and/or something else?
