I know one feature Siri has added in the past fifteen years, because I always complained that Siri couldn't "text this photo to my wife." I would demonstrate to people that this doesn't work, complain about the lack of discoverability, and mention how with each new release of iOS I would try it again to confirm it still didn't work.
Then one time, in a job interview of all things, (I'm a PM and was asked for an example of a product I liked or didn't like) I went into this spiel, and what do you know, Siri texted the photo to my wife. :-)
So somewhere along the way they did add that feature, and apparently I didn't realize I had missed checking for it.
They definitely do change things and not always for the better. I used to start running/walking workouts from the Apple Watch telling Siri something along the lines of "let's get running!" or "let's go for a walk" to which it would react starting the right kind of workout. Since WatchOS 26 it tells me it doesn't know where I am and something about privacy settings, and that's it. Asking in robot mode it does work though: "start running workout"
