On Commons (and some other wikis), we're still tracking Statements as part of the "Other" usage aspect. We may want to consider changing that.
```
wmf-config/InitialiseSettings.php:22343:'wmgWikibaseDisabledUsageAspects' => [
wmf-config/InitialiseSettings.php-22344- 'default' => [],
wmf-config/InitialiseSettings.php-22345- // disabled statement usage tracking wikis
wmf-config/InitialiseSettings.php-22346- 'commonswiki' => [ 'C' => 'O' ],
wmf-config/InitialiseSettings.php-22347- 'cebwiki' => [ 'C' => 'O' ],
wmf-config/InitialiseSettings.php-22348- 'warwiki' => [ 'C' => 'O' ],
wmf-config/InitialiseSettings.php-22349- 'hywiki' => [ 'C' => 'O' ],
wmf-config/InitialiseSettings.php-22350-],
```
**Acceptance criteria:**
* [ ] figure out why this wasn't enabled on Commons (and those other wikis) when it was first introduced in T151717, [db07845](https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/415264)
* [ ] get an idea about what impact this would have in terms of database usage
* [ ] get the ok from the DBAs
* [ ] enable Statement group usage tracking on Commons
**Notes:**
This was discovered while looking into T186716.
