There is no problem with MD5 that makes it unsuitable for this particular application. A SHA signature would enlarge each packet, further reducing the effective MTU. This would increase the cost of what was intended to be a simple mechanism to solve a specific problem (spoofed SYNs/RSTs).
Ignoring valid RST frames breaks TCP.
