The iscsi-gw has lacked a maintainer for quite a while.

If someone really really needs to run iSCSI, they might check out

Clients that can't talk NVMe/TCP? E.g. some BIOS implementations? Certain 
VMware releases?

RBD through libvirt is an all-around better solution for that.  Fewer moving 
parts, less overhead, lower resource utilization on the Ceph side.
