Make an Excel Add-in instead of the VBA module
Introduced with v0.11
It doesn't necessarily mean that the VBA module has to go away... but for anything but deployment, an add-in would probably be easier as you wouldn't have to update all the Workbooks that rely on the VBA module with every new package release.
It would be harder to deploy. The great advantage of the module is that it is much easier to send the file to a client (for example). To be honest, I think the module thing is the competitive advantage xlwings has over the competing technologies.
I think this would be an excellent idea making it less verbose.
