And the federal government issues effectively binding guidelines for the cap design of baby food. The upside? Windows don’t fall out into people and babies don’t choke on the caps.

Nothing in the linked 14-page window replacement guide has anything at all to do with safety in general or windows falling onto people. It is entirely to do with preserving the "historic character" of buildings. I don't think you can reasonably equate that to the regulations governing the design of caps on baby food.
