Scenario:
I have some (multi-value) field, selected with some Core Field formatter that has a settings form. (Example: link field in our standard tests' link paragraph.)
These have settings, e.g.
field_link:
formatter: raw
name: link
is_slot: false
weight: 0
region: content
configuration:
is_slot: false
settings:
trim_length: '80'
url_only: '1'
url_plain: 0
rel: 0
target: 0
Now, in the respective "Manage Custom Elements" tab, I change to "Raw" formatter, save and export the CE display.
The "settings" sub array is not removed from the exported values, even though it is unused.
Prune the 'configuration' array, sometime. (Just before saving, or at an earlier point.)
Make sure 'is_slot' is not inside the configuration array; only the 'outer' is_slot value is used/valid. (Hint: 'name' is not duplicated, don't know why)
Active

Code
This might be done after 📌 Change configuration structure for CE display 'components' Active is done.
Also / related / check: we should just remove the whole 'hidden' section if #3455435 didn't do that yet.
