All this tells me is they didn't want to say why they rejected you, lack of a required experience is a benign excuse.
The reality might be you were too old, too young, too smart, too stupid, wrong race, looked like the guy who ran off with the managers wife, who knows.
I would never expect to learn anything from a job rejection, or for that matter from a lost sale.
I've been rejected from numerous job attempts and I learned a lot from the majority of them. Whether it was the lack of fundamentals on data structures and (sometimes) stupid algorithmic interview questions, or a CTO with whom I totally clicked but the founders just didn't get me, or "ew, I'd kill myself if I had to work in this office", most of them were learning opportunities.

It isn't always (or even usually) the case, but it does happen.
When I was looking to leave my first development job (where I was the sole developer at a very small non-profit) I made sure to highlight during interviews that I was the only developer. Two companies let me know they were passing on me largely because of my lack of team experience. After that I didn't overly emphasize the fact I was the only developer and had three offers in under a month. [And sure there most likely were additional factors but the point is you can get meaningful feedback from a rejection].
Exactly. After all, are they supposed to "excuse" it at all ?
"Sorry <dude>, you are a really strong candidate and we were happy to talk with you, but in the end we decided to go forward with other candidates that are a better fit for the profile we are seeking."
