Could columns using TIMESTAMP not be changed to DATETIME to avoid the 2038 limit?
I know this project wants to keep support for MySQL 5.6, but from what I can find DATETIME should work there as well?

Unrelated: I've had zero issues with MariaDB (11.4 LTS currently), so maybe that could be a potential default to target at some point in the future.
