It is always better to optimize a table with indexes, if you have valuable performance data and analysis please reach out to either the Alliance Auth or Community dev responsible for the data that could benefit from indexes. MySQLTuner will likely recommend increasing this number for as long as there are any queries that could benefit, regardless of their resulting performance impact.
Also keep in mind this is _per thread_, if you have a potential 200 connections, 256MB \* 200 = 50MB, scaling this setting out too far can result in more memory use than expected.
