Ok, you were addressing MOD's that support SS only, fair enough. The way I read your reply was that SS is so little supported by modders as to be negligible, which if nn- is to be taken at face value is obviously far from true. Regardless of that, this whole RFC is comical to read as literally no data was presented to support the proposal to drop SS, other than of course it requires effort from the development team to add in the new features and is overall regarded as a "PITA" (based on anecdotal remarks from a handful of people.) Ok, so do a plus and minus column weighing the costs/benefits of dropping it. You should not add or remove features of a product without measuring the value added or lost from doing so.
The supporters of dropping seem to be saying that it will save development time by not having to maintain it. Okay, how much development time exactly will you save? Years? Months? Weeks? Days? Hours? Is it a significant amount of time and resources that clearly offsets the negative impact to the user community using SS styles? (It would have to be a fairly large time savings to even compare to the staggering amount of boards that will be affected, just an fyi

)
Another reason for dropping it was
It causes extra work for MOD authors to support two very different templates - many don't even bother support both templates
MOD authors are
not required to support SS today, so how exactly does this force extra work for them? It seems to me that if they wish to only support PS they are free to do so and the user who wants to use a MOD without SS instructions has to figure it out on their own or ask for help <-which no one is *forced* to provide. Seems quite fair and reasonable to me.
Yet a third reason was given as
Keeping two very different base templates up to date with MODs is a lot of work for users
Pardon, but isn't that choice the users? There is no requirement that boards running both style templates keep them up to date, unless they wish to. If they feel it is too much work they can quite easily not update one or the other and stop using it. I am not sure how taking away the ability to choose helps the users.
To be honest MOD's should not have even been a factor in the RFC as MOD's are an optional add-on and have nothing to do with the core development process. Since .com does not require SS support from MOD's, they should have no bearing in a discussion regarding SS's continued existence.
