Given the cycle created between numeric->decimal and decimal->numeric, I can pretty much guarantee they will. In any case, I don't think implicit casting from numeric->decimal is a good idea since it can overflow. I'm not sure that the other direction is safe either... I can't remember offhand if casting correctly obeys typmod or not.
BTW, have you talked to Pavel about making these changes to his code? Seems a shame to needlessly fork it. :/
yes, he talked with me, and I gave a agreement to continue/enhance/fork this project how will be necessary
