Migrate: Create term(s) if they do not yet exist Question similar to this question here, but this time, I am not doing a separate migration later.

I want to create taxonomy terms if they do not exist while processing a record. Does entity_lookup do this in the same way migration_lookup does for stubbing? In this case, I won't be doing another migration to fill in a stub, but surely there must be a way to create a term and keep going. 

I don't see anything in entity_lookups plugin indicating it will create if not found.
Wow, ok, getting better at parsing the docs/code for migrate plus. I found it as soon as I posted. The entity_generate plugin will do this behavior.

  field_paper_jel_codes:
    plugin: entity_generate
    source: jel_codes


Now I have a system full of taxonomy.
