Yup. And if you have multiple goals, such as heritage and effectiveness, then you'll have a longer list. At some point if your list of required pros is too long or specific, you may have to decide what's more important. Or figure out a way to get it. So if I really really want to learn wushu because I think it looks awesome, that might be something I'm not willing to give up. But I also want to learn how to actually fight. But none of the wushu places near me teach me to fight. I now have to decide which is more important. I can train wushu and give up on combat effectiveness, or train MMA at the gym next door and give up on the cool flips and flashy sword stuff.They are not mutually exclusive and so the water gets muddied there.
Quite often an art that teaches heritage uses that heritage to support its effectiveness.
So I may do krav maga because I think Israelis are cool. But I don't do krav maga because if the Israelis do it it has to work.
Or I can do both, so I learn both things. Or train wushu and then compete in amateur MMA fights and dog brothers fights to learn how to actually apply it. So without them teaching me combact effectiveness, it doesn't mean I can't learn combat effectiveness, so long as I know that's not what I'm getting going into the school.
