mount – Support for additional file systems on Ubuntu Core

I'm trying to mount an external hard drive formatted with exFAT on Ubuntu-core (Raspberry Pi edition with instant package manager), but there does not seem to be any way to install the required packages (exFAT fuse) .

There is apparently an existing support for fuse interfaces on snap but I can not find any current implementation of it (not to mention exFAT).

Am I missing something?
