Calling RAD Studio a high-quality IDE seems like a stretch to me. I would choose VS Code or a JetBrains product any day of the week. Unfortunately you a kinda stuck with it when developing in Delphi.
(And VS of that era was rather meh...)
VS Code isn't.
The closest i've seen elsewhere is QtCreator littering the code with red error messages about the unknown symbol while i'm typing the code together with a lightbulb next to the line with it which, if i click on, it adds the #include.
From a technical perspective the ability seems to be there, it just doesn't feel as smooth and seamless. Not to mention all these errors that appear while i'm typing make me anxious - like, STFU, i know the code is wrong, i'll fix it once i finish typing this part :-P.
