The problem with this is which developers? People who write embedded systems? Web developers? People who write custom Windows applications?
Any given developer subset is likely to find this hypothetical new developer computer to be either too complex to use or not differentiated enough from Windows or MacOs (or ChromeOS).

This is not true for most people whose primary employment is writing software, or working on software teams. Most people who get paid to write code work primarily in either the Java or .NET ecosystems and use something like Eclipse, IntelliJ, or Visual Studio. (Many more are using niche-specific tools in a captive platform like Oracle, SalesForce, SAP, etc.) If the new platform doesn't have 100.0% binary compatibility with legacy tools written for Windows and/or MacOS, its addressable market shrinks substantially.
