I think that the designers of the amps are extremely knowledgeable and aware that they could dampen the tubes. But they choose not to. The only way I personally would do this is if I used different model tubes than they installed and microphony itself caused a horrible change.
No harm in trying it out. It is all about what you want. If it gives you s more unique sound, that is a big bonus.
