I enabled strict sql mode in MariaDB for an website just last year, after noticing the database was silently corrupting data. What made the transition much less painful was noticing that when strict sql mode is disabled, MariaDB produces a warning for the queries that corrupted the data, but you must run SHOW WARNINGS; to see the warnings after running such a query. Knowing that, I made the website run SHOW WARNINGS; after every database query and logging if a warning occurred. This allowed me to deal with the most of the warnings before they were promoted to errors by enabling strict sql mode.
