I'm pretty sure that the main reason why devs in the past just wanted to create new content is that they wanted to put it on their CV to make it look pretty for the next job.
Fixing old stuff don't look good enough on the CV and is barely mentioned. I think that's the drawback from developing a game in a major game hub like Montreal.
It's great that it now looks like the devs have a longer term plan with what they're doing.
