Why Are Some Parts of Import/Export Settings excluded

As a dev one of the hardest things is switching between systems, from old to new because the tools I depend on inevitably opt to leave out some portion of what needs to be included when I'm moving software between systems. 

Its 2019 and yet with Windows I am still unable to easily/reliably move software between 2 systems and get everything in the process without some level of manual intervention on my part and I'd like to know WHY?

If you are looking for what new features to add to your products then might I suggest that Red-gate take the lead to be a trend setter in software by creating the first software tool(s) that can actually be moved between systems and everything the user needs and relies on is included so there's no manual cleanup need by the user to complete the move.
