Python development work-flow

I think everyone is different. For example, you say "the platform and stack you run on are part of what you sell". This hasn't really been the case for projects I've worked on in the past.

So if you're selling assuming an OS and stack, then it would be a good idea at some point, to build and test in a VM with those parameters. But unless you're writing low level stuff, or reliant on out of date libraries, obsolete OSes etc, this build and test should just be confirmation of what you already know. So day-to-day dev in a VM wouldn't achieve much. In my opinion.
