No, but avoiding potential errors by not duplicating text strings is a
worthy effort, as we learned long ago from relational database theory.

What FITS did not learn from relational database theory was how to
create mechanisms which document and enforce the self consistency of
data which have been neatly separated into distinct logical chunks.

I think that's the way forward.
