    Description

      Based on heap dump analysis of YANGTOOLS-652, SchemaPath instances are taking up 11% (13% with partial YANGTOOLS-1065) of retained heap size.

      The problem is that SchemaPath is used in quite a few places to provide type inference and we do not have a replacement mechanism.

      Hence we first need to add that mechanism, then deprecate/migrate SchemaPath usage and finally kill the ill notion of a SchemaPath.
