 ## Behavior matrix
 
-The table below shows the resulting behavior for all combinations of the two feature flags.
-
-### Only `enable_samples_on_show_sample_rows_tags: true`
-
-| Level | Tags | Samples shown? |
-| --- | --- | --- |
-| model | none | No (hidden by default) |
-| model | `show_sample_rows` | Yes |
-| model | `pii` (only) | No (hidden by default, PII feature not active) |
-| test | `show_sample_rows` | Yes |
-| column | `show_sample_rows` | Yes |
-
-### Only `disable_samples_on_pii_tags: true`
-
-| Level | Tags | Samples shown? |
-| --- | --- | --- |
-| model | none | Yes |
-| model | `pii` | No |
-| test | `pii` | No |
-| column | `pii` | No |
-| column | `show_sample_rows` (no pii) | Yes (excluded from PII columns) |
