Reading the following Fedora workstation group (?)'s document about hibernation, it seems that Fedora doesn’t support hibernation by the following concerns.

hibernation is less power consumption than S0 or S3;
But …
Note 2: There is a pernicious problem with laptop batteries. As they age, they often won’t tolerate load very well, leading to rapid discharge and very short or no notice before a compulsory power off. In such cases, even when the system is hibernation capable, hibernation can fail. Power can be lost during hibernation entry. There isn’t much software can do to second guess the commonly confused state of aged batteries.
Current significant impediments:
- UEFI Secure Boot is overwhelmingly present and enabled by default on new computers;
- kernel lockdown policy inhibits hibernation when Secure Boot is enabled [4];
- ACPI bugs can be transient and difficult to fix or work around; hibernation can mean data loss due to failed entry or exit;
- resource requirements for the permanent swap partition can be excessive, Anaconda history states the reason for the current swap partition size [5] is to accommodate hibernation;
- large swap partition exacerbates performance problems in swap heavy workloads.
