There was a problem hiding this comment.
These limits are totally arbitrary, I don't know what numbers would make sense here.
Another approach I thought about was to increment a loop counter, and use the same limit for structs and updates. It might be preferable because 100_000**2 = 10B loops is also too many. I don't think this would work for GC and skip item lengths, though.
Happy to iterate on the solution!
