Checking it again, I also noticed that there is a slight play. If I hold the cranks on each side and try to wobble it, there is a small wobble and clicking noise with each wobble. Maybe 0.5-1mm wobble? Is this also negligible? Its not something that I notice or hear when I ride at any intensity be it standing or while sitting on the saddle.

So, it's showing wear, but still workable. Since nothing you do will make any difference, ride it as long as it works and replace if/when convenient. In situations like this, I buy the replacement so it's on hand, but keep using the original until I can't.
