Lol sure does if you ask me. I hadn't even realized until you brought it up, but Gnome 2 was my first ever DE way back when I tried Ubuntu for the first time nearly decades ago. Time sure flies!
Moved the panel to the top, added a dock (rip latte, it's now just a panel) and set a hot corner for the overview effect. I like it to move windows between desktops.
Everything else is default though. Maybe I changed the application launcher widget, I don't remember.
Personally, not. The reason I switched to Plasma is that I didn't like the basic layout – horizontal bar especially – and wanted a desktop environment that allowed me to customize positions and sizes of bars and so on as much as possible.
Still baffles me why they steal the screen's usually scarce vertical real estate with a horizontal bar, instead of putting it on the side...
I've gone through Gnome 2, Unity, Cinnamon and nowadays tend to favor KDE and honestly, I pretty much always try to replicate a traditional experience no matter which of them I'm using, so pretty much the opposite of what you're asking, I suppose. I'll say I did appreciate the top left corner quickly exposing all windows, so that feature I try and replicate whenever possible.
