multiple simultaneous read-only imports of a static zpool?

I'm curious if multiple hosts could have simultaneous read-only imports of a zpool on shared disks? The pool would be exclusively read-only during concurrent access so there would be no issues with cache coherency, metadata and so on. Is this possible? Has anyone tried it?
 
Sure, I definitely understand that. But what is the problem with the scenario I described? The data on disk is static and the hosts would import read-only. Each host always has correct knowledge about the zpool. Apart from potential inefficiencies, how could this be a problem?
