I chatted with @pirama-arumuga-nainar about this. My takeaway is that the team is more focused on broader platform optimizations right now and this may not be a high priority due to it's application specific requirements for profiling. We would be happy to consult and review Android related changes (e.g. sanitizers) if needed. Pirama please correct me if I'm wrong. 

@SharonXSharon Do you plan to go ahead with this work? We would like to have the common format changes landed so that we can use it on ELF while ensuring your use case is supported.
