i have the opposite impression on mini-camps. Why does my whole entourage show up at all of my mini-camps? it's ridiculous. So i have a bunch of pets, a weird skeleton, etc all following me around everywhere I go? it's ridiculous.
That is why I want us to get a main base so that the entire entourage doesn't follow us. Whereas after we get a main base we are limited in our minicamps to our active party members, maybe 2 backup party members, and possibly a couple service providers that make sense to travel.
Everyone else would start to populate that main base which would become the hub for the rest of the entire game. Any recruited non origin companions, merchants who want to go there, and NPCs like Volo or the Talkative Skeleton would reside in that base, fixing up their sections and making it feel like a proper homebase. And when people are dismissed they do things there. For example gale and other wizards could occupy the library researching and studying things, Halsin or another druid would be in a garden with plants, etc etc.
And when you want to switch people out you go to that main base and do just that.
Then again I am someone who wants a ton of non-origin companions, and having a base slowly populate with them would be beyond awesome to me.
