Some common requests for new features:
1. Namespaces for classes, as seen in C++ and Java
While this is commonly requested, is it necessary?

Of course it is not necessary. But like variable scoping in blocks it is quite useful in practice and leads to better class names.

How is it useful in practice? Apart from "looking nicer"? What problem does it solve? At what cost? Comparing my experience in Java and Objective-C, namespaces don't really seem to add anything of value.

Example: instead of using
---
@interface OGoWebUIScheduler
---
@namespace org.opengroupware.webui;

@interface Scheduler
---

Looks way better to me. Of course this is just a "visual" thing - just like [a setObject:b forKey:c] looks better than a.setObjectForKey(b,c).

To me, this is actually significantly worse, because now the name is no longer descriptive. You seem to have mixed up two separate concepts, prefixing in order to avoid namespace clashes (OGo) and using a descriptive name ( WebUIScheduler). While the first could reasonably be replaced by a namespace, replacing a descriptive, intention-revealing name with something completely generic like "Scheduler" seems like an awful idea to me, just like I *much* rather have -addObjectsFromArray: versue -add:
