I remember reading that bleeding brakes without a piece of wood under the brake pedal would casue a tear and resultant MC leak, but couldn't locate it during a search. Can anyone point me to that? Thank you in advance!
Also, why would the brake system be designed such that it results in damage to the MC that way? It would seem that someone would actually need that extra couple inches of travel in an emergency. It doesn't make sense. Mismatch of replacement parts perhaps?

It's not about a design issue but a corrosion issue. Over time the areas of the MC that are not regularly stroked by the MC piston will develop deposits and corrosion that can damage the piston seals. It would probably not prevent a one time severe brake application but could result in a sinking pedal after that.
