I'd say there wouldn't be much point to it at all.
19 squadron themselves reverted back to the Ia from the 'experimental' Ib pretty darn quickly, even though they had to accept some pretty weary Ias that came I think from an OCU.
Nope, far more issues to address than this very minor thing.
Has anyone mentioned that (visually at least), none of the Spits have metal skinned ailerons? These only came about post November 1940 and have about as much importance to the current game as having the true Ibs supplied to 92 squadron around the same time.
Operable nav and landing lights, now I'd welcome those.
