In classical music, the composer and the performer (musician) are two different individuals, and a single piece has many different interpretations and recordings by different people - both the composer and the performer are what builds a unique recording.
In current osu! convention however, the Artist field is just taken by the individual artist (example: beatmapsets/1187093#mania/2474006). This is confusing, as the actual composer is hidden in the tags. A parallel could be drawn to modern songs where a composer writes songs for an artist, and then the artist name (usually singer) is used in the Artist field (or Composer feat. Artist) - however I believe the classical situation is different enough to warrant a specific indicator, as the artist and the composer are completely separated and independent, a performance is not a "cover" as there isn't an "original recording" or "original release".
Proposal:
Example: In the previously linked beatmap, the Artist field would be "Maurice Ravel (perf. Jean-Philippe Collard)".
This is not a common situation in osu! as there aren't many classical pieces being mapped due to their timing difficulty, but some examples do exist and I believe it would be good to include this standardization, as the current situation is not well handled by the existing Ranking Criteria.
EDIT after some discussion: Added "Various Performers" edge case.

Proposal:
In recordings of classical pieces, the Artist field should indicate both the Composer and the Performer, using the standardized indicator "Composer (perf. Performer)". If the length of performer names exceeds the field character limit, "Various Performers" should be used.
Example: In the previously linked beatmap, the Artist field would be "Maurice Ravel (perf. Jean-Philippe Collard)".
