The translation_entity module added the concept of a "default_operation".
It is only used by User (which has 'profile' and 'register' instead of 'add' and 'edit').
While #2014821: Introduce form modes UI and their configuration entity wants to continue to use the 'default' operation, #2006348: Remove default/fallback entity form operation plans to remove that.
The compromise is to make 'default_operation' more widely used and/or mandatory.

plachSounds like a good idea. At least it will remove yet another weird ET one-off :)

amateescu commentedPosted a patch in #2006348: Remove default/fallback entity form operation which includes this proposal, so maybe we should mark this as duplicate?

tim.plunkettAs much as I wanted to have "Make X a thing" commit message, that's fine :)
