It's not so easy. MySQL has a large legacy of being used as a very-immediate-although-somewhat-toy database at its roots. For example, in absolute terms, I would find much more troubling the usage of non-transactional tables, justified by meaningless microbenchmarks, which has been somewhat common for some time. Nowadays MySQL is definitely reliable, and it has a much more expert surrounding culture than the past, so if a person/company is willing to put time and knowledge, it's a reasonable choice. I don't find automatic conversion so damaging that people should stay away just because it's default. When you reach some level, you definitely need to have a relatively intimate knowledge of your tools, and at such point, one is far from the "defaults".
