My opinion on worms. They cannot live or will not necessarily stay in a potted plant long term, so they're pointless there. In the natural garden, they will or won't be found there depending on many different factors and those change thru the year. They are not essential to a garden. They don't 'cause' composting, they eat products of food rotting or of the compost process. I find worms at various times in my outdoor compost.
My daughter showed me her bag of 'indoor' potting mix, a yellow bag but not a familiar brand.
Edit, almost positive it was this Kelogg

Bag says forest products, etc I think it was very much forest products. Aka partially composted shredded tree waste.
Texture was weird, dried to sort of fibrous hard clumps, she said when pots were watered they leaked brown. I think, as others here on site have complained, that the bagged garden product market has become hit with inferior products.
