They should be relatively stable, since they appear in the URL (e.g. https://brc-analytics.dev.clevercanary.com/data/priority-pathogens/phenuiviridae-prototype-pathogen-viral-family) and we want people to be able to link to these pages. Does it make sense to pick the pathogen (or pathogen family) as the slugs here ? @d-callan can you take a look at this ?
