Its important in legal issues to make a reasonable attempt at precision, just hand waving "and others" isn't appropriate.
I'm don't know Latin, and am not a lawyer, but I believe that ["et al."](https://dictionary.cambridge.org/dictionary/english/et-al) is legalese for this exact use. Also, it's technically more precise to leave some of the names and abbreviate it with "et al." rather than deleting the original details and replacing with some ambiguous group like "Geany developers" or "contributors". But again, I don't really care.
