I think the main issue is that there's no easy way to "see" how the allocations scale across LLVM in general. How many of them, where they are done, how many per sec., diff. against a previous build, etc.
We could implement a system to "tag" each allocation and save it along with the callstack. It would then easy to save binary snapshots and inspect where the allocations go, do diff-ing, etc.
It just takes someone that has time to do it ;-)
