Expanding the "FragmentSpread Selection" causing reusing Fragments ineffective

[AneethAnand]

Issue Description

We are facing an issue where queries to subgraph services blows up astronomically. I have created an issue regarding this before and have created a temporary solution to auto fragment. (#2457)

But with all the latest changes to make Reusing effective, I still see major issues. From my analysis
I see that the FragmentSpreadSelection has been expanded and I dont see ...GroupFields fragment spread or Fragment in my subgraph schema.

Can you please help resolve?
