Short description of error
Rigify allows you to "Relink constraints" and then you can create a custom constraint and name it etc... a core feature for the MetaRig to expand on the existing rigging.
The Tool Encode MetaRig to Python does store the setting "Relink Constraint" showing that it is on but doesn't store any code to save and reload the constraints that have been created and setup to for relinking. So if you have to delete and rebuild the MetaRig or if you want to save the custom meta rig to build from, all the constraints that are created for relinking get lost.
Exact steps for others to reproduce the error
Create a meta rig, pick the breast bone, turn on relink constraints and in pose mode add a constraint to the bone.
Swtich to edit mode and use the rigify tab to run Encode MetaRig to Python. The setting from Pose mode is saved that Relink is on but none of the constraints are stored.

Changed status from 'Needs Triage' to: 'Needs User Info'
Shouldn't constraints have special naming to make this work? I don't understand this myself, but the documentation seems to indicate that. See https://docs.blender.org/manual/en/latest/addons/rigging/rigify/rig_types/basic.html#basic-raw-copy.
I think this got fixed. This issue was about how the encode python script saves out the constraints that exist on the meta-rig. I can test it again but it should be working.
Raw copy is different. Relink constraints lets you replace targets with special naming.
Changed status from 'Needs User Info' to: 'Resolved'
Encode MetaRig correctly stores the constraints to the python script.
