for me id rather seat the bullets deeper and have the option of making them longer later.
Why would that be max length already? You have the entire length of the neck and depending on the cartridge that can be a lot of room to work with. As the throat erodes you chase it. By the time you run out of neck it's probably time for a set back at least, maybe a new barrel. Keeping the bearing surface above the neck/shoulder junction seems like a good idea to me, it's generally what I base my specs on when I order reamers.
