SQL Server is still community supported, and we have IIS 7+ in our “server requirements”, which won’t change.
But the WebPI installer is rarely used in practice, and doesn’t provide the best user experience for Windows users
compared to other installation options. Given it sucks up time on every release process. this should be removed.
Once you get a few sites under your belt most devs would likely turn to using environment files to names DB credentials. This introduces this a bit earlier to get them used to the simple idea of an environment file.
Eventually I'd like to rewrite the installer to generate this over storing in the _config.php.
