Oops, didn't mean to be too too negative.
I say embarrassing in the sense of, I've definitely shoved out awful code because something needed to get out(tm). And with large companies, deadlines that cause that situation are inevitable.
But I also say it like that because, well, I've seen code that causes (objectively easy-to-fix) crashes but still ships because of one reason or another: laziness, politics, inexperience. It's a part of software engineering I'm still trying to accept.
Yep, there are lots of small services that don't seem production ready in the source code. Though admittedly we don't know which of those are deprecated.
