Don't you think the reverse is true? 1.5 is compatible with 1.4,
unless you use some specific features not many users use anyway?
(Though maybe they'll start using them now that they're safe to be
used...)

Yup. irretrievably lost. No way to recover. So, that means at some
time we'll need to bump the wc format number to be able to use depths.
