Proposal: Permanently disable rule SA1409

[sharwell]

Rule SA1409 (RemoveUnnecessaryCode) has two characteristics which make it a particularly poor rule for StyleCopAnalyzers:

• It is poorly defined (what is or is not "necessary"?)
• It is largely a semantic rule as opposed to a syntax-based style rule

I propose rule SA1409 be permanently disabled, and allow other tools which focus on semantics (e.g. a future "FxCopAnalyzers") to pick up this diagnostic at a later time.

I agree. This should be handled by something like FxCopAnalyzers.
