I think you are coming at this with very different priorities. For most people, installing tool chains is a one time job, that they can grit their teeth through if it works well for them. No one wants to constantly install or reinstall and make sure the installation process is lightning fast.

It's the reason why Linux still hasn't taken off on desktop. People want good application support, not infinite customisations and blazing fast compile speeds. In fact, slow compile speeds might even give people an excuse to go chat with colleagues and take breaks. What you want is not what others want too
