ddorwin has just created a new issue for https://github.com/w3c/encrypted-media: == "tracked" sessions: Does "record of key usage" need not be updated each time a block is decrypted? == Pull request #54 specifies that the _record of key usage_ be updated every time a key is used to decrypt a block. I wonder whether we need to _require_ this level of granularity. We should definitely be clear about what authors can expect and the minimum granularity implementations must achieve, but I'm not sure requiring per-decrypted-block granularity is necessary to support the relevant use cases for the `"tracked"` session feature. The reasonable minimum granularity probably depends on when this information is persisted. Thus, this issue is blocked on issue #82. Issue #80, whether to track key or session usage, may also affect this issue. See https://github.com/w3c/encrypted-media/issues/83
