Sierra and apfs compatibility

[balooo84]

I thought sierra gets full read write support for apfs. Now i just read that :

APFS compatibility
Devices formatted as Mac OS Extended (HFS+) can be read from and written to by devices formatted as APFS.

Devices formatted as APFS can be read from and written to by:

• Other devices formatted as APFS
• Devices formatted as Mac OS Extended, if using macOS High Sierra

For example, a USB storage device formatted as APFS can be read by a Mac using High Sierra, but not by a Mac using Sierra or earlier.

Pretty disappointing as it seems we don't get even full read support, or am i missunderstanding something?
