There is good documentation 'out there' about how SD\SDHC Flash and Journaling works.
The journal repeatedly written to a confined section of the filesystem.

Not all SD's are equal, either in the quality of the memory cells or in the quality of the wear-leveling algorithm.
NOTE: these in-built wear-leveling algorithms can be incompatible with flash filesystems.
Personal experience has demonstrated once it is 'burned' the whole SD becomes read-only.

It should be the Users choice to enable journaling and risk SD destruction in preference to shutting down properly.
I recommend filesystem check at boot should be enabled with journaling off and disabled with journaling on.

PS: Being Raspberry Pi specific, I do not know why Raspbian does not use F2FS, but that does not exclude Devuan from using it.
