There is a simple answer to all this. My last two employers us a procedure called "Special runway procedure" which applys to both take-off and Missed approach. The Company has assessed each runway for obstacles that cannot be cleared with normal procedures. Those runways that have an obstacle problem have been submitted to Jepperson for them to design an escape procedure/path that will give the maximum payload capability all the way up to LSA. This procedure applies to both departure and arrival and secondarily the resultant RTOW's for the runways also provides the MLW.
I also aggree with some of the previous comments and the whole question is a legal minefield and therefore it is encumbent on the operators to be able to prove if necessary that they did everything they possibly could to prevent a misshap.
Have a nice day
