How much software genuinely requires not having a GC? If you don't want it, don't use it, but using it can make your software completely safe and fast (Garbage Collection is often faster than RC as long as pause times are acceptable, and added memory use).
A lot of the standard library ranges are inherently lazy and therefore require no interaction with the GC. Exceptions are also nogc now.
