Yes, but the more you have, the more the programmer has to understand and keep 
track of. There's cost in cognitive load. So, you want to add enough that you 
can do what you need to do and get some solid benefits from the attributes that 
you have, but at some point, you have to stop adding them, or the language 
becomes unwieldy. Whether it would ultimately be good or bad with regards to 
unique specifically is still an open question, but it means that any attributes 
you add really need to pull their weight, especially when we already have so 
many of them.
