I'd also say that being a T shaped person is how I'd try to be „hirable“ as a generalist. Get really good at one thing that has a title (in my case: „Data Engineer“) but also have a broad range of skills.
Sometimes it sucks to be T-shaped. Imposter syndrome kicks in all of the time :)
Doesn't it get balanced by the occasional „Why do I have to show you how to do your job“? ;)
I've never been in such situation. Usually it is expected from me to do it all :)
