Ok so garbage collection is optional, how about garbage generation? Is there any way to manually clean up resources if GOCG=off, or will memory usage continue to grow unbounded as new objects are created?

Grows unbounded. I wasn't recommending that one should set GOGC=off. Just making a remark that one could should they choose to do so.

EDIT: Sorry, I misunderstood part of your question. The memory grows unbounded unless you call runtime.GC() which triggers garbage collection. But this is a blocking call and essentially block your whole program.

I think in theory you can write code (or do some tricks) to avoid all heap allocation.

"In theory" being the operative words there. Turn on heap escape analysis sometime, you'll be surprised how hard it is to avoid.

You mean not growing the heap or literally no allocation?
