The llvm-symbolizer is not using this format but asan_symbolizer is:
see https://llvm.org/svn/llvm-project/compiler-rt/trunk/lib/asan/scripts/asan_symbolize.py

search for class BreakpadSymbolizer(Symbolizer):

I feel this should speed symbolization considerably!

However, old path should still be there for local builds. Or maybe we can always generate that breakpad info during profiling builds? 

Agree, old symbolisation should works as-is.
Also, these files are not public available, so it will not work for a local build off-corp.

I super-approve, especially if you say that is faster (not surprised, the dwarf data addr2line has to traverse is insanely complex)

About symbol fetching I left some notes in Issue 740045. Not sure whether that is useful, up to you to figure out the best strategy to fetch symbols.
