IIRC, that has been Delphi 6 or 7. One can even test for that with {$IF CONDITIONALEXPRESSIONS}.

It was Delphi 6. (That's one of the reasons why GExperts dropped support for Delphi 5).

You still need   {$IF Declared(RTLVersion122)}  if you want the component to also work on 12.0 and 12.1.   And $IF is not supported on earlier compilers, if that matters.

Using {$IF (CompilerVersion >= 36)}TListSize = NativeInt;{$ELSE}TListSize = Integer;{$IFEND} is compatible also with 12.0 and 12.1, because in System.Classes property Items is already defined as [Index: NativeInt] (they missed to raise a warning in 12.0 and 12.1)

The Project Options in the Delphi 12.2 IDE does not even support such option, does it? (I want to disable the warning in dproj files)

No.
