Pls see Bug #927221 against gvfs-fuse, in particular Mr. Simon McVittie's comments. For fuse and fuse3 to be co-installable, changes need to be made to handle the file conflicts for mount.fuse, fusermount, and fuse.conf. Pls see my comments on how Arch and openSUSE have handled that so that fuse[2] and fuse3 are co-installable on those distros.
