The developer (balbes150) is actively working on s912, but sometimes he updates s805 (more often Armbian than LE).
He posts about s912/s812 here: Test LibreELEC images with KODI-18 for S9xxx
and, as stated here: Test LibreELEC images with KODI-18 for S9xxx
he is still considering s805:
"... All my images now use only the new kernel 4.x (might be an exception for S812\S805 to release the base of support in the mainstream kernel)".
