I didn't mean that every Harmony JVM should follow OPEN interface. It
is not necessary to implement but maybe JVMs can benefit from
following it (or any kind of standard interface accepted by the
community). It is just a proposal with some simple ideas behind it:

First, JVM should be modular. Second, those modules should have
standard interfaces (and therefore, be reusable in other VMs).

If you don't agree with this approach or have any other thoughts about
the proposal - please share it with the community - your opinion and
your experience is valuable.

I believe this document was made so large not with the intention that
nobody would read it but just because of the complexity of problem and
an attempt to clarify all issues :)
