I don't actually see why a modified version of this cannot be made... We can copy the apfs.efi from Mojave and use it with the same patcher, no? Don't have a non-APFS machine to test this on but it seems like it should be doable. For those who don't want to risk a Boot ROM patch (I sure wouldn't).
Agree, probably Mojave APFS EFI script patch is doable, at the state of art it has already been done with Clover bootloader that has some variant of apfs.efi and apsfdriverloader.efi , but using Clover on real Mac is much more riskier than an APFS ROM patch on multiple EFI CHIP ID definitions.
Anyway to those who are not hungry to upgrade weekly their current Mojave beta, the Mojave Patcher offers the big chance to re-create a current USB Installer with HFS+ Installation, just refreshing it as
@TimothyR734 has pointed some posts ago.
I would say luckily those who are on Mojave HFS+ don't run the risk to be forcedly converted into APFS drive resulting into an unbootable OS, so that's why is always useful to keep another previous High Sierra HFS+ (or minimum Sierra 10.12.6 HFS+) partition that is still capable to read/write an APFS volume to recover personal files in case.

Got my SSD and installed it and installed Mojave on it no issues. Will format to APFS after moving all my files. Would it be smarter to have my HDD run El Capitan and use it as an external storage and have only Mojave on my SSD, or have a partition of my SSD be El Capitan and use my HDD as a Time Machine disk? I currently have no time machine backups, never needed it, but would it be smarter to have supported El Capitan on it or turn it into a time machine backup? Got no replies a few days ago.
I would keep a small partition with El Capitan on the internal disk, or better if you can, try to install a (Patched) Sierra 10.12.6 HFS+ that is the last MacOS capable of read/write and use Disk Utility on an APFS Volume container.

After testing on my end, I cannot get Software Updates in System Preferences with a logical volume formatted as HFS + (macOS Extended Journaled). I then restored and "upgraded" it to Apple File System (APFS) and I received the Developer beta 9 update. Should I report this as a bug? Or is this a deprecation on their end?
[doublepost=1535428460][/doublepost]UPDATE ON MENU BAR BUG REPORT:
Engineering has requested the following information in order to further investigate this issue:
Are you using a GPU with Metal 2 support? Is so, please provide the model of the GPU card and its serial number. If the Mac has an integrated Intel Graphics Card, please provide a macOS sysdiagnose.
They asked for Metal 2 ? This does not promise anything good.
Don't worry your IntelHd4000 has minimum "GPUFamily 1 V3" set (check System Profiler/Information Graphics/Displays), while from Mojave it should have "GPUFamily1 v4" set, Metal 2 fully supported, so answer to them quietly. Be vague with them, send a screenshot of this zone "GPUFamily1 v4" System Information GUI app, GPU serial number should be "Device ID/Revision ID" or easier type this from Terminal and save into TextEdit file sending to them the resultant strings:
system_profiler SPDisplaysDataType
