This will need some follow up changes. The class name for example is not unique. Same class name exists in:

client/ayon_core/plugins/publish/extract_thumbnail.py
client/ayon_maya/plugins/publish/extract_thumbnail.py
client/ayon_hiero/plugins/publish/extract_thumbnail.py
client/ayon_blender/plugins/publish/extract_thumbnail.py
client/ayon_max/plugins/publish/extract_thumbnail.py

This will also need thorough testing whether it does not conflict with logic in certain DCCs like e.g. the ones mentioned here that also roll their own Extract Thumbnail plug-in.

Testing notes:

1. Extract Thumbnail should work
2. Extract Thumbnail should not cause issues in any of the DCCs/integrations.

NOTE: We should also find out why the representations are being removed here if they have "delete" tag. That looks as potential rist.

I think the other DCCs are using in-DCC logic for thumbnail extraction. E.g. maya viewport.
