 From the result point of view, perhaps, but definitely not from the 
build perspective. ;-) But yes, I understand this is functionality that 
should be kept.

So build support for trivially adding specific charsets to specific 
platforms? Both to java.base (for AIX) and jdk.charsets, I presume, then?

Can you expand on the issue of dropping ebcdic? What's the problem that 
needs build support?
