If left, they will do as you mention and produce very small bulbs - some might even go to flower. How about leaving some and splitting others? You will then be able to see the difference and won't risk losing the lot. If you do split them, remember to water them well while they grow new roots.
Yes, you may well as leave the spring onions and treat as 'cut and come again'.
