Curious - Why does Unity 2020 import unrelated assets on package import

In the case of this screenshot:



What does HydroForm materials for instance have to do with trying to import Gaia Pro 2021, and so on. It's actually above 6 and a half minutes so far but the point is it eats so much time.

 

bump! I'm using Unity 2021.3 and this "unrelated assets import" is triggered as well.
I do an asset conversion with The Vetegation Engine, but it trigger importing for my whole huge projects, everything.
Please Unity, this problem is ongoing for a long time through many version, since 2019.

 

Maybe the assets add some type of processing to materials so this needs to be done when importing them.

 

I eliminate the issue by making new project and copy my assets folder to it.
