Why shouldn't they be? It's better to have them and not need them than need them and not have them.

Yes, brake spring pliers may be gong the way of the dodo bird (extinct), and carburetor adjusting tools but, they can be useful even though some don't work well on bonded brake shoes.
Below is a picture of two pairs of brake pliers and a wilde brake tool. The wilde tool was like $3.00 at Epsteins and is a great investment.
Back to the pliers, the larger set was a limited run KD made update to the age old design. Instead of the large c shaped fulcrum jaw ending in a point, KD added a red rubber coated pad for use on bonded brake shoes. On the old style pair the point of the fulcrum jaw would go into the rivet hole to provide leverage as you stretched the spring. The little rubber coated pad prevents you from damaging the friction material. There are also two different sized replaceable hooks on the other jaw. A nicely designed pair of brake pliers that I have never seen anywhere else beside the flea market i bought them at years ago for a few bucks.
I can't find my extra set of Kent Moore spring pliers made for the single heart shape spring found on late model GM vehicles. They have j shaped handle for pulling outward on the spring, a pointy handle for the small spring, and long notched jaws for spreading shoes for wheel cylinder replacement. very handy.
On a side note, although everyone has done it, you want to be careful using side cutters or vise grips on brake springs. The vise grips create a flat spot on the round wire spring, and dykes leave a small nick or notch. Both areas are weak spots that may lead to spring failure down the road. think of how many time those springs expand and contract during the life of the brake shoes and you'll replace them at every brake job.
