Another idea is to add some specific tags by the mulitpolygon algorithm that link to the other pieces of the formerly big forrest. This could be evaluated by the SizeFilter?
Another idea (don't know if this is possible):
You have a big multipolygon forest. You could duplicate it. One copy without small inner polygons for the low resolutions. Another copy with the inner polygons which gets splitted for the higher resolutions. The copies could be marked with some mkgmap internal tag and used later.
May I propose to move the whole multipolygon handling to the filter chain? Then there is _no need_ for additional tags and duplicated polygons and possible remerging of them. The filter chain is run for each resolution level. With each run the poylgons could be handled accordingly. I don't think, your ideas are wrong. I appreciate your work. But I think its made more complicated than actually needed.
