It looks as if “MSFS Addons Linker” has the Advanced ability to have OFFICIAL content supported …
ie Official content is moved to a defined Addon-Linker "Official"Folder, and then those items can be “Turned on / off” to be loaded into MSFS, just as other items can be, that are in the equivalent (typical) Community holding folder for Addon-Linker.
Trying it out now (its advanced / experimental), but so far the only issue I see, is that once moved, MSFS “Content manager” does not see them as being installed, so any UPDATE of them gets into a mess ?
Unless there is a better way, the only way I see around this is to Occasionally “temporarily” move them back, when there is an SU or WU.
The big ADVANTAGE, is if you don’t need them, they are no longer detected or loaded/checked by MSFS, making boot time shorter, and maybe less loaded in sim, but when you do need them, (ie WU Japan, if you choose to fly today in Japan), then you have them already downloaded, and all you have to do is enable them in Addon-Linker for that Japan flight (15 seconds vs 30 minute download )
Not much info on this feature, so any community input would be most welcome …
