more generally i would say: repetition of objects, groups, or instances, is a common pattern in pd. and there are certain ways to do it (select, route, multiple inlets, and so on), but all of them require a lot of patching (proportional to the number of instances you want). why souldn't exists an object which does this for you?
it is possible to make crippled substitutes like nqpoly or rabin/clone, but it is not possible to introduce proper multi-abstractions without a major redesign of Pd internals.
The main obstacle is that Pd maintains only a single monolithic dsp graph. Breaking that would not be easy now: there are optimizing hacks in dsp graph handling, plus various patches in the code for features like resampling, etc. These are all great, but they make the implementation quite complex, and nobody seems to dare touching it.
