Last time I looked, it didn't even allow installing apps from outside AppGallery at all. Also, I don't think the Huawei services are any less intrusive than privileged Google Play.
I am fine with AppGallery apps only lately. Did so for the last year on my Android Huawei.
First - a lot of things are just not on there. And second - not allowing alternative sources gets really bad when said store is asked to censor apps, like, say, proxy clients or alternative social media apps (Newpipe, etc.).
