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.

Thanks @snehasish and @pirama-arumuga-nainar for following up on this! @yozhu from our sister team is currently working on this internally, he should be able to answer the questions of upstreaming plan.

> @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.

Yes definitely! Sorry for the delay, have been sidetracked by psc, summer break etc.. Will try to continue in the following weeks
