Well put, it's definitely a matter of taste. I think you have made a spectacular platform, so no offense intended to your tastes. To get a look at very high quality aliasing without sacrificing performance (at least not 10x) take a look at this wonderful library, AGG (anti-grain geometry).
It is all native code C++, no GDI+. Performance with a good compiler that targets a modern CPU architecture should be very good. Worth keeping in mind that these charts are not as intensive as 3D animation, afterall they are not updated that often, with the exception of scrolling, and you can only scroll one chart window at a time (albeit it may have many indicators in it).
I agree if you did it, it would make most sense to be turned off by default and optional.
