System.Threading.WaitHandle implements IDisposable at least since MS.NET 1.0 

Some System.Runtime.InteropServices interfaces prefixed with _ were added in 
MS.NET 1.1 SP1 for more proper COM interop support.

Another exapmle is System.Web.HttpResponse.TransmitFile method that was 
added to MS.NET 1.0 and MS.NET 1.1 by a hotfix and later Service Packs 
include it:

Regarding such post-RTM API changes I suggest to implement the API of the 
latest MS.NET Service Packs available because this is what people usually 
use and Microsoft probable evaluated the drawbacks of such changes and the 
should be fully backward compatible.
