Leo, We partitioned Harmony contributors a long time ago (based on prior access as declared in the ACQ), so while you state it as:
> * there are people who want to only ever work on a small part of > the codebase in fact there are people who only *can* contribute to a part of the Harmony codebase, and some of those will be fine people that become committers (right George ;-) ?) and we should welcome them. Beyond such restrictions, I agree with your comment that Harmony committers must keep a watching brief over the entire project. The size of this project is set to grow considerably if/when the DRLVM is accepted and we tackle new areas of the class library etc. The number of committers has to grow too and I expect there will be a natural grouping of parties around the VM, JIT, UI, performance, etc. I doubt any one person will be in a position to scrutinize equally all changes in any part of the code JCHEVM, BootVM, classlib, DRLVM, JIT, GC, etc. So reading your mail carefully -- I agree. I'm comfortable that we are not prematurely splitting Harmony beyond the lines already drawn in the project, but I support the work to ensure that the lines remain distinct since we can predict that such specialization is very likely to occur.
