Even after reviewing all this information, I'm still unsure where my leanings are on this matter. On the one hand, with the built-in mod support, it should get mods up to date faster...but to do so would require some mods to literally start from square one again, it's sounding like, or at the very least, a considerable amount of rewriting.
Or maybe this is just the ramblings of a semi-sleep-deprived computer jockey who's reading into things too much.
Yep, some rewriting must be done, but at least its for the better.
