Should we ignore the nodes that are deprecated in kg2c build process?

[chunyuma]

Based on the KG2.6.1c (http://kg2canonicalized.rtx.ai:7474/browser/) that @amykglen just built, I found that the nodes which are labelled as deprecated in KG2.6.1 are still used in KG2.6.1c. There are total 42,431 deprecated nodes in KG2.6.1. Should we ignore these nodes in KG2c build process?

match (n) where n.deprecated='True' return count(distinct n.id)
count(distinct n.id)
--
42431

Here is one example: In KG2.6.1, we have GO:0075020 which is labelled as deprecated

But in KG2.6.1c, it still exists there.
