I stands for "Integrated" in IDE. Project generation, code inspection, source control, database access, refactoring, debugging, test running, etc are integrated.

Visual Studio Code generates project via third party tool - dotnet new. Refactoring, code completion is done via third party tool - Roslyn (?). Etc. It's an editor with plugins. Unlike Visual Studio or Jetbrains Rider.

So Eclipse isn't an IDE either because all functionality is in individual plugins?

Eclipse always been resource hungry sublime text java clone.

Are you saying Sublime Text existed prior to Eclipse?
