Not directly affected by this issue since I'm not using mbox for any
production system nor have I for many years. And it'd take a lot of
effort to convince me to use mbox for anything someone would even dare
to classify, even remotely, as "production". But if I understand OP's
point of view correctly, he's not arguing necessarily for or against a
specific mailbox format. Instead, he's flagging a regression and people
will be very reluctant to upgrade or even adopt a certain feature in a
new release of a product if regressions are seen as acceptable.
Something that previously worked in an otherwise unchanged environment
stopped working after an upgrade and this is a regression. Trying to
convince people to move away from mbox is a very sensible approach, I'm
all for it, but in cases like this not practical.
