And I think I have said it before but would like to say it again that personalty I would prefer and vote for to stay with the current scheme. IMO this version jump is quite confusing for most new users and does not really make a big difference for all the users and developers that are following the development more closely. For example explaining every time again and again if a feature or a bug / regression was introduced in version 0.17 or 0.18, but that this are actually one and the same version,... I am afraid it will bring more problems then solutions
I guess the scheme was popular some time ago (in 2004?!), some projects are still using it, but I don't really see many new projects starting or switching to it... It also makes no sense to use it in some of recently more popular rolling releases (continuous delivery).
