What exactly is the downside and for whom?

The British Empire was already collapsing rapidly when the Open University was founded in 1969. I doubt that ensuring a supply of ship masters was a motivation in choosing to include trigonometry in the syllabus.

Sure, if you want to believe that Open University invented a brand new pedagogy rather than continuing a traditional style of teaching trigonometry that had been honed over the course of 150 years of naval power projection.
