Maybe it's changed a lot statistically in the last few years but for long time PC gamers used to have the mantra of small SSD for the OS and large HDD for games if they're price conscious so I could see that being assumed to be much more normal during development.
It's a shameful tragedy of the commons if you bloat your game 6x because you think your customers don't have enough SSD space for their active games.
