Incorrect TLE submissions should be allowed to give WA about problemtools HOT 2 OPEN

A note: this should cut both ways: a WA solution should be allowed to give TLE on some test cases, as long as it gives WA on at least one test case. (And the same thing goes for RTE submissions.)

Note that there is a small but non-zero risk that allowing this will allow some human errors to slip through the cracks. For example, if the input format changes, it might cause a WA solution to do undefined things, sometimes giving RTE and sometimes giving WA; with the current behaviour that would be detected and fixed. There may be merit in having some opt-in mechanism (like a magic comment in the source) to indicate which outcomes (other than AC and the goal) are acceptable.
