Found this in the Liquorix web site forums. Looks like he hasn't got round to it.
Why are zram and zswap no longer configured in 4.0-1.dmz.1-liquorix-amd64?
I need them!

I disabled them thinking they contributed to the stalls that braveheartleo was affected by. However, after reading the description and reading some feedback, they look safe to keep enabled.
For example, zswap only compresses to swap partitions and zram has to be enabled specifically by the user. Since swap is normally slow, it should cause the system to stall _less_ due to the compression reducing the total number of bytes needed to write to disk, easily by a factor of 2. As for zswap, that's up to user discretion, so it was not my business to disable it.
Next release should have zswap and zram restored.
This seems quite important for users with hybrid and SSD drives.
