I think it should be removed because:
1. The config is LUT based so is less accurate than the analytical implementation.
2. Due to the many LUTs required the installation size is 430Mb. If 1.2 config is removed only ~100kb remains.
3. ACES Reference Gamut Compression is only available in the OCIOv2 configs.
4. OCIOv2.x has long superseeded v1 with more flexibility.
5. ACES 2.0 is around the corner and will cause 5 total entries to the OCIO config list for just ACES as color management option.
ACES 1.2
ACES 1.3 Studio
ACES 1.3 CG
ACES 2.0 Studio
ACES 2.0 CG
This is way too much imo. ACES 1.3 should remain there for legacy reasons. The DRT is completely different and many productions may linger for a bit more on 1.3 once 2.0 has arrived. But we don't need 1.2 there anymore for a long time already.
For projects created with the pre-installed ACES 1.2 configuration a message should pop up that this config is depricated along with a link to where it can be manually downloaded from to be loaded into AE via custom path.
