What if I want a car I can choose to drive occasionally because I like driving? Will I have to buy a manual and a self-drive? (Although to be fair, these self-driving cars would probably suck to drive since they are not designed for driver pleasure)
What if I want an oven I can choose to grill with because I like grilling? Will I have to buy an outdoor grill and grill by hand? (Although to be fair, these electric ovens would probably suck to grill with since they are not designed for charcoal grilling enthusiasts.)
A better analogy would be that of a grill that can use gas or charcoal as the fuel; different means to the same purpose.
