It's just that a signal inlet doesn't know what to do with a non-signal 
input, and a non-signal inlet doesn't know what to do with a signal input. 
There's not much reason why the look of câbles wouldn't be different 
depending on whether they carry floats vs symbols vs whatever else. The 
GUI could also try to assist you more by investigating more about which 
connections don't make sense. There is a hint that Miller had such a thing 
in mind at one point and ended up not implementing it. You can see it in 
how outlet_new is defined and used: most classes declare a type for each 
of their outlets. Currently this is only used for signal vs non-signal, 
even though many classes define outlets with typenames like "float", 
"symbol", "pointer", "anything", ...
