In the eighties, a lot of devices with very limited memory (from 1kB to 64kB) used garbage collection of sorts (kind of heap compaction). They were called home computers. It worked just fine.

Heck, people are running embedded Java with garbage collection and all with just a few kilobytes of RAM.

Low memory does not mean you need to do manual memory management. Of course, when you add requirements for predictable memory usage, it might be a different matter. Like embedded devices that need to run for extended time periods reliably without issues.

But then again, a lot of Commodore 64 programs written in BASIC managed to do just that without issues. Running for years without hick-ups.
