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.
