• Should the VirtualSMC Plugins section clarify compatibility for every plugin, or only those which are not 10.8+?
• Should FakeSMC still be recommended as a fallback for legacy users?

As I was advised:

• Should the VirtualSMC Plugins section clarify compatibility for every plugin, or only those which are not 10.8+?

Yes. Actually, all the plugins had compatibility ranges other than 10.8+, so specifying was required in the end.

• Should FakeSMC still be recommended as a fallback for legacy users?

No.

Other changes in the last commit is that the minimum version of WhateverGreen was reduced to 10.6 as Arrandale kext patching is now supported.

Beyond VirtualSMC and its plugins, AppleALC also now has 32-bit/legacy OS support. However, most codecs do not have patches for older OSes, so further guidance will be requested from @dhinakg and @khronokernel for how this will be handled within the guide. After this is reconciled, the minimum version will be lowered to 10.4.

Finally, 32-bit building was broken for CI builds (and thus release builds) of VirtualSMC so the 1.2.6 release binaries do not have 32-bit support. Merging will have to be delayed until VirtualSMC has 1.2.7 released and AppleALC has 1.6.4 released.

Now that the September round of releases has come and VirtualSMC and AppleALC have both had new versions released, it is now safe to merge this.

EDIT: One question still remains however, which is what to do with the AppleALC note. AppleALC does now support legacy versions of macOS, however the vast majority of codecs need patches created for older versions.
