Code Issues Proposed changes

Remove all references to deleted change fields

Browse Source 
We had lots of hard-coded logic to do slightly different things
depending on which version of a particular field was present in a
schema. For every field that has now been completely removed, we can
remove references including these bits of extra logic.

The difference is especially striking in the sortkey query path. Note
that queries containing sortkeys have already been failing since
servers upgraded to schema version 8 (2.9), which no longer uses this
field.
