If lots of things change though... Couldn't that be a smell of bad boundaries? Like the change would not have been so drastic with the right abstractions?

  It could be the smell of bad boundaries. But sometimes a data type can have many functions that work with its internals. The 75 functions might not sounds so bad if there is a good justification for their existence, and there are 7500 other functions which don't have to change which rely those functions. At some level we need to actually implement things; we can't have abstraction all the way down! I'm also reminded of Alan Perlis Epigram #9: "It is better to have 100 functions operate on one data structure than 10 functions on 10 data structures."
