Creating a new race was a major accomplishment as well as a major responsibility.
To be fair, a lot of human biotech researchers invented artificial species all the time. There was much to gain from creating a new race that possessed interesting properties or performed better than more ordinary organisms.
The overwhelming majority of new species never saw the light of day. They were mostly grown in labs and usually took part in numerous experiments throughout their short lifespans before they were unceremoniously 'recycled' in order to reuse their biological matter for the creation of a different or improved species!
Only a tiny proportion of artificial species and organisms were deemed adequate and profitable enough to be put on the market.
