I don't see the complaint as "it's wrong to use powerful chips in a cartridge". As has been pointed out, even contemporary cartridges did things like that. I see the 'complaint' is that there's a creative/artistic appeal to seeing what can be squeezed out with limited/constrained resources. Or, at worst, does it make sense to use an old console like the Game Boy if you're going to use such a fancy cartridge? I'm reminded of the MythBusters episode where they tried to make a cannon from a wooden log. They resorted to using modern power tools. "I'm not doing anything they wouldn't have done if they had access to these tools!". I think the project is pretty cool, anyway.
