Provide .Net 4.0 Framework support for SharePoint
Provide .Net 4.0 Framework support for SharePoint 2010 so that .Net Framework v. 4.0 projects can be built and deployed to SharePoint 2010. In addition, a new/updated set of Visual Studio project templates should be introduced with the newest .Net Framework v.4.0 support.
.Net 4.5 is now supported with SharePoint 2013. Not sure if they will update SharePoint 2010 to support .Net 4.0 at least....

I think Visual Studio is not the problem. I'm not sure about exact .NET version SP 14 uses, but it's somewhere betwen 2.0 and 3.5. All of these versions use the same CLR (2.0 introduced in .net 2.0). .NET 4 comes with new CLR.
Every application pool in IIS must have CLR version specified. As far as I know, it's not possible to run assemblies using diffrent CLR version in one application pool. It's IIS feature.I don't think it's possible to bypass that

I asked the SharePoint guys at SPC if there was any feedback system; they pointed med to the forums.
We seriously need .NET 4.0 support! My company has been developing in .NET 4.0 for the last year, just to find out that it's not supported in Sharepoint. We just installed sharepoint and everyone seems so keen about it ... apart from us, the developers, that need to see how to circumvent the problem of platform incompatibility :/

Does SharePoint have a similar feature suggestion system? If so, where?

This doesn't have anything to do with Visual Studio 2010. It's more of a feature request for SharePoint
