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.
I only go there, usually via an external link, to install new apps or to check for updates for already installed apps.
Google Play is usually way too slow for my liking with applying updates automatically. They tend to sit there for a day or so and are not getting installed for whatever reason, even though they have already been detected.
I haven’t ever seen a useful app in my recommendations, it’s always apps from big tech companies (i. e. Facebook, Instagram, WhatsApp, Spotify, Snapchat, …), which I have sub-zero interest in.
