I don't think hiding behind a 'anonyomous' tag is good, but I also think the artificially accelerated risk of flying a perked plane is bad. 
 I think range based identification is a good compromise. 
 Icons displaying the 'base type' until 1.0k, and then displaying 'specific type' under 1.0k - ie. a Ta152H displayed as '190' up to 1.0, and then switching to '152' under 1.0k... or a Spit14 displayed as 'Spit' to 1.0k, and then 'Spit14' under 1.0k.
 I think that will actually bring a very interesting aspect concerning the skill level of a pilot - a pilot with a sharper grasp of things might spot out a Tempest, or a Ta152 earlier than others by judging how the opponent is doing;
 for instance "hmm, that 190's got awefully long wings.. must be a 152!".. 
 
  or
 "hmm, that Spitfire is way too fast for a Spit9.. must be a Spit14!"
 Meaning, the detail level of info the icon displays is limited, and in ranges where the icon may display 'faulty' data, a pilot with a higher skill level might be able to perceive through it. 
 I think it'd be interesting...
