Not from the company but we do something similar with opentelemetry. It’s true, because you pay for the total allocation of CPU/memory on Fargate, so you can add a sidecar container into that total allocation with a small deduction from the amount left available to the app itself. E.g. Before: 512MB for task, 512MB available for the application After: 512MB for task, 412MB available for the application, 100MB available for sidecar

Yes, but even in your example, that's 20% of resources going to the sidecar. Not to mention sizing correctly multiple containers in a single task gets complicated.
