Nothing stops you from simply not enabling that font feature, user config is also not a bug
Which editors on which OS's provide a toggle for that?
Sublime Text: Set "font_options" to "dlig". There are other settings to choose which character tables are allowed to use ligatures or not.
Visual Studio Code: Set "editor.fontLigatures" to "true". You can also put CSS font features to choose which ligatures you want to enable.
And then you run Vim or Emacs in said terminal...
