Michael McCandless commented on LUCENE-9049:
--------------------------------------------

This can also be a heap reduction for Lucene apps that create many fields, 
since those cached root arcs were allocated in heap, but the new 
direct-addressed arcs are now off-heap (usually?).

> Remove FST cachedRootArcs now redundant with direct-addressing

> With LUCENE-8920 FST most often encodes top level nodes with 
> direct-addressing (instead of array for binary search). This probably made 
> the cachedRootArcs redundant. So they should be removed, and this will reduce 
> the code.
