I'm not that sure option 2 will really blow up the tile size and CPU cost. Today, most people creating a map use a very huge number for --overlap to avoid this kind of problems. And how many multipolygons are really that big that they go over several tiles?
I fear the administrative boundaries and coastlines.
You are right, this could become a real problem :( I think the coastlines are already incomplete for europe if you don't work on the planet file. Since they are no longer closed, would they really end in every tile? Of course if you have an extract for great britain, or even more worse, for complete north america. Especially in the last case, you will have about 1500 tiles all containing the boundaries and the coastline. Maybe the solution would be to merge mkgmap and tilesplitter and do the split on the processed mkgmap data. But I don't know enough about how this works to know if this is doable at all.
