Font Substitution & Fallback
In general Patched Fonts are not necessary required, because several systems support font substitution and/or Fallback fonts
The EUDC feature of Windows can be used to define a fall-back font that will be used for Glyphs that are not found in the current font. This means that a single Nerd Font can be installed on a Windows machine, and the Nerd Font glyphs will then be shown for all other fonts in the system without need for patching other fonts.
