Thanks for your concern, albeit rather late There's much more to it than you suggest unfortunately, Kyeman and myself experimented with them for a while during one of his short periods on the team, but rewriting major parts of code, with the impact that would have on the rest of the code, and the testing requirements and stability risks inherant with totally new methods being 'crow-barred' in made it unrealistic to continue with them. Especially once the new core started to take shape. (which of course supports boats fully without need for messy hacks nor rewrites).
