Subject: [PATCH] fix: update full list of index options

Back-port of index options from master. In 3.5 this list was a block-list, and in 3.6 and 4.0 was updated to be an allow-list, but missing the complete list of options. This caused an issue where we accidentally dropped support for language options.
