Now that T243051: A query builder for MediaWiki core is done, this extension should migrate away from IDatabase::select() to SelectQueryBuilder.
It would improve readability of the code, avoids mistakes by passing the wrong order of arguments, etc.
For more information check T243051 and its documentation.
Note that query builder is a different paradigm and changes should not be one-to-one. For example, avoid using joinConds().
