Append-only would imply yes. There is no overwriting in append-only. There is only truncate and append.

[mosselman]

You have misread I think.

There used to be append-only, they've removed it and suggest using a credential that has no 'delete' permission. The question asked here is whether this would protect against data being overwritten instead of deleted.

[ThomasWaldmann]

Yes, it also disallows overwriting.
