There is no answer on record and nobody holds a position, because the evidence to hold one was never gathered. Wilhelm Bleek and Lucy Lloyd recorded /Xam between 1870 and 1884 and their work ended when their narrators went home and no further speakers could be found. The neighbouring communities of the southern and eastern Cape were recorded by no one. Their languages have no speakers and their descendants were absorbed into other communities. The San religion described in the scholarly literature is therefore the religion of the /Xam and of a small number of twentieth-century northern groups, generalised, and the generalisation covers an absence rather than a consensus.
What would resolve this Recovery of further colonial-era linguistic or missionary material comparable to the Bleek and Lloyd notebooks: unpublished mission-station vocabularies, magistrates' and travellers' notebooks, or word lists held in South African, Dutch, German and British archives that have not been catalogued as linguistic material and so have not been looked for. A systematic archival survey aimed at this specific question has not been carried out. Failing that, the question stays open permanently, which is itself worth recording.
