It really depends on if the 10-year-old code in question was put together by a talented team with high standards, doesn't it?
But regardless, on a large project, you're always going to have some version of this problem. At least when you yourself are getting in there and writing and understand the code, you have a half-decent shot at debugging in a reasonable period of time. When even you are vibe coding your additions to the pile, you're all the way back at square one when shit hits the fan, trying to learn it all from scratch.
