I don't think anyone is arguing that the diodes are the best solution to the problem long term, but they can be done now with minimal cost and effort, and will help protect your hearing.? They will also cause no problems when the eventual polished solution is released as they only have an effect at very loud audio levels.
I'm not super concerned about "bodging" a radio that is home built to begin with - I always considered that part of the fun so long as the modifications were made well, but an external adapter would solve that problem for you, and you only have to worry about forgetting it until the polished firmware solution is released.
