AWS::EC2::Route CloudFormation resource does not verify the gateway type

I was playing with CloudFormation trying to create a private subnet that uses a NAT gateway. When declaring routes, I made a typo in the template and used GatewayId property instead of NatGatewayId when defining a AWS::EC2::Route pointing to the NAT gateway:

PrivateSubnetRoute:
  Type: AWS::EC2::Route
  Properties:
    DestinationCidrBlock: 0.0.0.0/0
    GatewayId: !Ref NatGateway 
    RouteTableId: !Ref PrivateSubnetRouteTable

When I tried to create a CloudFormation stack with this template, CloudFormation did not report any errors about an invalid gateway. Instead, the PrivateSubnetRoute resource remained in CREATE_IN_PROGRESS state for about 20 minutes, and then creation failed with the following error:

Resource handler returned message: "Exceeded attempts to wait" (RequestToken: bcf33526-b64a-9781-7e22-f4330a941fa2, HandlerErrorCode: NotStabilized)

I'd prefer CloudFormation to check the type of the specified gateway and return a meaningful error if it's not correct.

Here's the full CloudFormation stack to reproduce the error:
