For about the 6 months of development of the protobuf based format in
Drizzle this is what I did, with a healthy number of asserts() comparing

For MariaDB, it would mean that when you were doing this you had two
things that could break and when you finally stopped the legacy format,
that would be a very clear break in any on-disk compatibility with MySQL.
