Oh I see, I had considered the author inactive because they haven't logged in for 3 months and the addon hasn't had an update in 9 months. Mea culpa.
I also thought that it was a simple matter of adding another name to the little list (not bolded as main author, just one of the other names) and that they could also update addons - that would've been an easy solution, but apparently it just shows how little I know of (maintaining) addons, hehe.
