Try explaining that to the dude who inherited the workbook in 9 months who doesn't know what Anaconda is, barely knows what Python is and was told that his job was Excel which he's really good at because he did a Udemy course on it 3 years ago.
I'm not sure why that is a problem. He didn't have to know anything about Anaconda. And for stability, you can still install 10-year old python 2.7 packages from Anaconda.
I would assume that workbook would be tied to a version that it was created in and the if the user does not want to update they can just continue using it with the older Anaconda distribution. They don't really need to know what Anaconda is in this scenario. It only becomes necessary if you want to update a certain workbook to a newer version.
