not bad idea, but realise, that almost each of member is using his own version system. And you do not want from some newbie to follow one precisly system, even he/she do not knwo about that. So perhaps like a recommendation for people is this usefull, but for the rest not. Myself I am going to use my system in future, just number of version 1,2,3 etc and second number if changes are not so important (1.1, 1.2 etc...)
