No reason to stop. As you observe, much work is needed there. The generic directory has the sparsest content, and for those of us arriving late to the party, the intended structure is only dimly perceived. > I thought it should be some kind of method > "frobenius_charpoly" or something attached to a hyperelliptic curve > object, and I was trying to find out what already existed.

"Working heavily" is overstating it. There were several people looking at the schemes directory during SD14, but there was not much progress. Most of the work was in the scratching of heads...
