"Tradition" and "traditional" are not univocal. Probably never have been. Persons have traditions, families have traditions, communities have traditions, etc. Word means something a little bit (or a lot) different in each context.

Probably the only words that get used consistently with a single unambigious meaning are found in legal and technical documents.

Ordinary language. Forget it.

Definitional disputes don't get interesting until money is involved.
