I have certainly done that (not with your code, AFAIK). The problem with
those beautiful one-liners is that they are really hard to debug. So if
I can't convince myself that they are correct just by reading them I
have to split them over multiple lines so I can add breakpoints or log
messages. Of course I could put it together again afterwards, but I
would argue that if I didn't understand it the first time it's probably
better to leave it in its more verbose and debuggable state.
Of course I have also done the opposite: Taken some messy and
complicated code and simplified it into a simple generator expression.
In fact I would say that I code tends to be shorter after I fixed a bug
than before.
