Not really planned before it gets out of staging and into the proper kernel, but maybe you can present convincing use cases.
Well, it is available in Debian experimental but that is really what it is "experimental" since it is in the staging area of the kernel.
My use case is that I run a few virtual machines in Virtualbox and if using a small 256MB zram as swap it helps avoiding getting the virtual machines and the host swap having to compete for the hdd.
The machine has 2GB ram and with 2 VM of 512MB each I tend to get some 200 or so of swap usage. Not very critical but if one VM gets some heavy hdd activity well everything gets sluggish.
But ok you might be right should wait for it to leave staging.
