We nearly always travel with a dinghy, started back in the days when we had the big dogs aboard, carried over to subsequent dogs, etc. But even without the critters, we find it very useful.
(We even have ours rigged so I can launch it in an emergency with just a couple of line slashes.)
But FWIW, we began working the "how would we carry it" issue during our mothership shopping stages. IOW, we selected a boat that could carry a dinghy, one way or the other.
It's also possible to sort it a bit more by picking a dinghy that speaks to the "how must I carry it" question. More compromises here, but generally solve-able.
"Systems of systems" approach.
