What gets compiled?

Yes, with virtuals being removed it won't be possible this trick:

the API
[pascal]
type TTestClass = class
procedure DoStuff; virtual; abstract;
end;
[/pascal]


The DLL
[pascal]
type TTestClassImp = class(TTestClass)
procedure DoStuff; override;
end;
[/pascal]

well this "trick" is totaly unsafe and shouldn't be used....2 different versions of the same compiler (or 2 different compilers for the same language ) "might" handle virtual method calls differently (VMT slot at a different offset)...if you want such behaviour, use interfaces instead - they will work the way expected on all compilers in the same manner (not taking into account calling convention or compiler/language-specific types)...
