If those spurs quit growing, they quit fruiting. They die when they quit growing. At that point cut them off.
I’d rather see a vegetative bud at the apex. Hopefully they grew this year and have flower buds. I don’t see many flower buds on the spurs, but maybe there are some.
Here are some stone fruits on K1, a very dwarf rootstock that really spurred up for me I think in the second leaf.

Look at the spurs on those plants in the top picture…!!
