To be fair Unity is somewhat special because it requires a lot more massaging to get acceptable performance in the happy path than standard C# code. In the latter you mainly care about large allocations if application is latency-tolerant (i.e. as long as you don't touch LOH it's fine) or avoiding allocations in general if it's latency-sensitive. There isn’t that much difference with regular sane C# code.
