Single-Use Caulk - Why not?

Nothing special here, just a single-use packaging design for caulk. But this begs the question, which products are appropriate for single-use packaging, and which should really be kept to more ecological full-size packaging? Caulk could go both ways, sometimes being needed for a quick fix and sometimes for a big-time installation. But is it a designer's responsibility to resist offering tempting single-use morsels in cases where they're not really needed? It would be great if such a "green imperative" had any influence on these kinds of design choices, but sadly, it just tends to be the need to sell more stuff!
