gnome-shell there is an extension that removes the window borders, close buttons, title bar, etc on maximized windows to save screen real estate.
How can this behavior be replicated in KDE?

To remove the borders of maximized windows in KDE Plasma 5, run the following commands:
kwriteconfig5 --file ~/.config/kwinrc --group Windows --key BorderlessMaximizedWindows true qdbus org.kde.KWin /KWin reconfigure
This is equivalent to doing the following:
Edit the file
~/.config/kwinrc to add the line:
[Windows] section, so that it looks something like this:
[Windows] BorderlessMaximizedWindows=true ActiveMouseScreen=true AltTabStyle=KDE AutoRaise=false AutoRaiseInterval=750 BorderSnapZone=10 CenterSnapZone=0
In older versions of KDE, the file may be located at:
Restart KWin by running:
If that does not work, try one of the following, depending on which display server you are using:
kwin_x11 --replace kwin_wayland --replace
Go crazy and maximize every window in sight! Remember that you can unmaximize them from the window menu (Alt + F3) or from the task manager in your panel. If quick tiling is enabled (System Settings → Desktop → Screen Edges → Window Management), you can also use Alt + Left mouse button to unmaximize windows by dragging them.
In Kubuntu 18.04, one can toggle borders (including the titlebar) and the maximized state of windows relatively simply.
In System Settings, choose Shortcuts > Global Shortcuts > KWin. In there, scroll to Hide Window Borders and set a shortcut. I chose Meta+D and clicked Apply.
Still, while in System Settings > Shortcuts > Global Shortcuts > KWin (in Kubuntu 18.04.1 LTS, Kwin corresponds to System Settings Module), scroll further down to Maximize Window. Here, I chose Meta+X and clicked Apply.
Obviously, I can use both Meta+D and Meta+X on the same window whenever I want.

In several applications --- Firefox, Google Chrome, Geany, Konsole are examples --- you can toggle borders (including the titlebar) and the full screen state of windows with the function key F11.
This works in Kubuntu (I tested in Kubuntu 18.04.1 LTS right now). F11 works also in standard Ubuntu and the other Ubuntu community flavours.
Go to System Settings->Window Management->Window Rules->New..
Add Window class choose “Regular Expression” from the drop-down and put “.*” in the input.
Click the Appearance & Fixes tab. Check “No titlebar and frame”, select “Force” from the drop-down, and select the “Yes” radio.
Save and close everything.
Your title bars will disappear but you will need to use the keyboard to close windows, minimize...
