Grant and Fred,
Isn't the reason we use sealer is because the gutta percha leaks?
Doesn't the gutta percha simply displace the sealer into a thin film
to minimize its shrinkage so that the sealer's properties are maximized?

Grant, Good post.
You are right; as gutta-percha leaks, why DO we continue to use it?
Because we can retreat it? Maybe Grossman's criteria for root filling
materials needs to be revisited.
The ideal filling material may be MTA. (NO, I don't own stock, yet).
After proper (and I mean proper) debridement & disinfection of the canal
system, place ~5mm of MTA. You can then back-fill w/gp (so a post can be
placed), back-fill with composite resin (which will strengthen the tooth),
whatever. - Fred
