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...
