I think the article is well balanced for when you can use a mesh and what the actual problem (heterogeneous tools) is.
What I think is missing is, that there is an underlying assumption that you can tweak each software you have in your environment, which might not be the case when you use paid software + self-programmed software + SaaS. The burden to configure each software to have tracing or mTLS is higher than finding out how each software might handle HTTP_PROXY.
So yeah, I am a big fan of gRPC with contexts, deadlines client certificates, but in an integrated heterogeneous environment you can only do so much.
At least this is my current understanding. If somebody has better/other experiences please help :)
