Intent to add support for cryfs

Hello,
I am using CryFS (https://www.cryfs.org/) in order to encrypt some
files in a shared directory. Before writing a policy for this software
and upstreaming it to refpolicy, I am wondering how this should be
handled.

CryFS is a software that can be run by non-root users that have access
to /dev/fuse. Its command is directly used to mount a directory
("/usr/bin/cryfs basedir mountpoint"), like command "mount".
Unmounting a mountpoint is done with "fusermount -u mountpoint",
/usr/bin/fusermount being a setuid-root program labeled mount_exec_t.
Currently, sysadm_t cannot use CryFS because it is not allowed to open
and use /dev/fuse (ie. fuse_device_t). Moreover labeling CryFS as
mount_exec_t makes mount_t require more accesses (reading a
configuration file from the base directory, reading
/proc/sys/crypto/fips_enabled, using pipes, etc.).

Therefore I am thinking of creating a new policy module for cryfs,
which could be shared with other similar software like EncFS
(https://vgough.github.io/encfs/). Does this sound like something
acceptable? Did I miss an existing module that can be extended in
order to support CryFS?

Thanks,
Nicolas
