By default, new server documents have extremely-conservative settings, and there are all sorts of config options and notes.ini params that knowing admins and DCT will tell you about. I get the value of keeping things eternally backwards-compatible, but it would be great to have an option to indicate that a server should use known best-practice options for a given release, so you don't have to keep up on what the appropriate NIF cache size for V11 64-bit is or manually add the latest "Create_RX_Databases" option, for example.
It'd be all the better to have named optimization modes for specific roles, too, to turn on things like
EnableImapFolderSynch for mail servers or
Enable_SNI for... well, anything with any internet protocols exposed.
