Hibernation requires physical swap at least as large as the RAM. The problem is, SSDs are prone to wearout when used for swap, and of course the PinePhone or PinePhone Pro (like all smartphones) does not have a magnetic hard drive, only SSD (FlashROM) storage (internal eMMC and optionally microSD; the PinePhone Pro also has SPI, used for booting only). So using a physical swap partition is not that great an idea, even if it may sound like one at first (allows hibernating, can help with the low amount of RAM). Which is why, as far as I know, all the distros use zram (compressed RAM as "swap") or no swap at all.
In addition, hibernation means the CPU is completely turned off, so it will likely not respond to wakeup requests from the modem, i.e., no incoming phone calls for you.
Those are the reasons why suspend (to RAM) is what everyone uses, not hibernate (suspend to disk).
