when I first did this for a project a couple of years ago, the github api endpoint for this sucked extremely bad. I no longer remember all the details but it was something like 3 different sets of things you had to get to make sure you had somewhat of a full picture. might be better these days. and even then it's still only the first piece in the puzzle

but yeah, by and large a rather extreme percentage of the modern industry is extremely dependent on a vary narrow scope of SPoFs, and may are clueless about how to even approach this. 2 decades of computer-renting, yay!
