Perhaps it's just that in some cases, the tool is overkill? In one case, I wrote a super simple shell script to track applied migrations to a database that had until then been managed entirely manually; I didn't feel like it was worth the trouble to try and learn something more complicated just for that use case, since it took me about 15 minutes to write a script that worked well enough: it applied the migration scripts transactionally (transactional DDL rules), in order and did so idempotently. Granted, I'm not a software developer by trade; just a sysadmin who occasionally uses programming to solve problems. I imagine if I had to deal with actual software development I'd end up learning one of those tools eventually.
