SDK csproj conversion and Web projects?

[Ariyara]

The CLI tool says the SDK upgrade should be done separately for web projects. The VS extension says ASP.NET framework projects are not supported by default in SDK style. Meanwhile AWS porting assistant doesn't care and converts all projects indiscriminately.

1 Does it mean the CLI tool to be used second time to separately convert web csproj to SDK style.

2 Does the conversion using the extension break the web projects.

3 Since the only core upgrade option for web projects is side by side, do these notes imply the SDK conversion is not necessary since the framework projects will become unused and the newly created Web projects will come with SDK csproj.

4 Is it a case of conversion potentially removing meaningful configuration in web projects.
