The problem is that each WMS requires a different CSV format. So you can't build a generic auto export which will work with all of them. Otherwise, we would have already done it.
It's a bit like payment platforms. They all have a different way of doing it. Thus, you can't be compatible with all of them, and you need to create one plugin for each one.
Because of that, it gets difficult to share the costs of development.
In that case, it's better to have the plugin done as custom work, either by us or other developers. Then, the plugin can be shared back with the community, either for free or for some money in order to cover the costs on the long term.
