Not if we want accurate field access counts, especially inside of containers. The MAX_HISTOGRAM_PRINT_SIZE is just for ease of debugging, as there is always a really large allocated block when running profiled binary with `env MEMPROF_OPTIONS=print_text=true:log_path=stdout:histogram=true`, which floods the screen with not so useful information
