I have a question about migration scripts: what are the best practices to maintain migration scripts? For example, we have a language with more than 50 migration scripts. We can't group them into different folders (because even virtual packages are ignored and all migration scripts displayed as a single list per language). We also can't remove them because our language has already a version and we have already created nodes that know about this version.
So my question is: how to deal with such kinds of issues?
