Why aren't Choirs treated as ensembles?

@support, I notice that many Choirs and Chorus are auto-assigned a “Choir” role. However, Choirs seem to be treated as soloist “Performers” rather than “Ensembles” by roon in various parts of its GUI. Probably because of the role mapping here:

Big orchestral and opera works often feature both an orchestra and a chorus and you usually want to see them together. But because an orchestra is treated as an ensemble whilst a chorus is treated as a (solo) performer this can require additional manual steps.

So, for example, in this case on the main album page “Accentus” does not appear on the “Performed by” line along with the other Ensembles. What I have to do is manually assign a “Vocal Ensemble” credit. Why is roon doing this? Is there somethng else I could do to avoid this manual step?
