The configs are litterally the same for 1080p25 and 1080p60 unlike 1080p30/1080p60,
so I don't see the point about duplicating a same table for the sake of naming.

We will the exact same thing to support the 2160p50/2160p60 modes by reusing the
same config are 2160p25/2160p50, and I don't see the point of duplication the
tables here aswell.
