Zombie pieces rule change proposal

Here is a rule change that I think would solve some of the issues that have come up:

Treat the pieces of a resigned/time loss/checkmated player *as if they could still move* for the purposes of check.

Example: Gold's king cannot move to square B2 because Red's queen faces down on that square. Red is then checkmated/resigns/runs out of time.
Current Rules: Gold's king can now move to square B2.
Proposed Rule: Gold's king cannot move to B2 until the queen is blocked or taken.

Some of the issues this might address: Several times the idea of having to only 'checkmate' a resigned king has been proposed and even implemented, no? However given their resigned state, bizarre conditions can result. If the pieces were still considered movable (even tho they wouldn't actually move) any checkmate would have to be 'real'... ie really deal with the pieces around, and the king.

Standard chess parallel: There is a parallel for this in standard chess. A bishop, say, which is 'pinned' in front of its own king, and thus cannot legally move, can nonetheless participate in a discovered check, or even be part of the block for a checkmate... *as if it could move*.

I don't think that zombies are a good analogy. Zombies are usually on the move, searching for brains. Since the pieces in your proposal would be threatening but immovable, I propose to call them Scarecrow pieces!
