Arenas don't require that you lose the ability to deallocate individual nodes. See my thoughts in #10444. Briefly, the idea is that the arena allocation returns an affine type like `ArenaAlloc<'self>`. You can then have a free method that consumes this instance and adds it to a free list to be reused for future allocation.
