<p>I'm certainly more convinced than ever by this that the <code>strong_migrations</code> advice to handle removing columns via two commits where you first deploy something to ignore them and then deploy a migration to remove them (which still needs to be marked as unsafe by the way!) is just crazy.</p>
<p>The fundamental problem is that it ties together the git history and the migration history so you have to execute them in sync with each other - this idea here is one result, and a second is that you can't go back and forth through such a migration without also rolling git back and forth at the same time.</p>
