This is one of the reasons I use Flatpak whenever I can. I’ve revoked all Flatpak apps the permission to access the root of my home directory via a global override, so anything they wanted to do in there (e. g. create folders, place malicious code in my ~/.bashrc, etc.), actually happens in ~/.var/app/<appid>/
.
I think they just aren’t sure how many instances you need right now (25? 30? all 50?) and that’s why they requested clarification for the actual resources needed. They don’t want to give you more than you actually need at the moment, so they don’t sit around unused for half a year until you actually use them.
