The classes and the names of some functions do not match!

For EXD.2(), EXD.3(), AR.2() and AR.3(), the class of the models specified is "Weibull" (as below)?

For example: str(EXD.2()) $ fixed : num [1:4] 1 0 NA NA

• attr(*, "class")= chr "Weibull-1"

I know that Weibull and exponential models are similar. Is it on purpose?
