Maybe we can simplify a bit to solve this issue:

• For development, instead of reading the addons from odoo/auto, we could read from odoo/custom/src (making the necessary adjustments to the addons_path configuration). We would loose the possibility of limiting certain addons with addons.yaml, but that is not that important for development.
• For production/staging environments, instead of symlinking, we can just copy the desired addons to the destination when building the image. It could even be a good opportunity to shift the approach a bit and rely on pip for that, as it would allow a better version management of the addons, and it is the method currently applied in OCA.

I would avoid always the pip mangling and its version managemente + addons path mangling.
