It may seem reasonable to you, but is there -legal- basis to do so? 

'signing' only provides assurance of the identity of the signer. I did
sign it.  The key has not been compromised.  The software in question 
is tracable to the signer, but the signer never claimed it was 'error free',
what conract or statute did they breach by doing the signing?
