Sounds like great news, no?
Just as we had a time before fungus digesting plant matter, we’ve now had a time before fungus digesting plastics.
“Soon” we’ll get bacteria and insects doing the same, and all our plastic buildings will need to be protected just as the wood ones.
Tl;dr:
Bathtubs started small due to size constraints of rooms, but got smaller because it’s cheaper to manufacture and handle smaller tubs.
