Ouch, are they really that stupid?

Using strnlen makes sense when a string has a maximum length, but when a 
string doesn't have one, it doesn't make much sense.

I would not do so, because this would not help detecting memory leaks 
either, but only shift the leak around.

Or differently: In cases like these, it's the callers responsibility to 
make sure the string is 0 terminated.

In case like these, this usually is the compiler.

Exactly.
