This feature means by default there will be no swap partition by default https://fedoraproject.org/wiki/Changes/SwapOnZRAM

Some folks might want/need disk based swap.

swapfiles:

• pros: easy to setup; no reboot required; supported on btrfs, ext4, xfs; removable
• cons: hibernation is sketchy. it should work on ext4, might work on xfs, does not work on btrfs (it can but requires a tool to find an offset, due to the lack of a standard interface across all file systems, for automatically finding the offset) https://lore.kernel.org/linux-btrfs/20200127192548.GA683123@vader/

partition:

• pros: no limitations
• cons: takes up space, isn't resizeable; more complicated/risky to create; requires reboot.

Notes: The installer's custom partitioning will continue to permit the creation of a swap partition and will configure for hibernation.
