Steve is a professional programmer and AIUI works on extended contracts, often away from his home. In addition I think he's had various other major responsibilities associated with family illness. So, all-told, I believe he's had literally zero time to think about VVP etc and seems to have made the decision to withdraw totally from commenting on VVP in forums etc.
TBH I think the situation with VVP in particular is fairly clear, ie it's a mature product when used as originally intended and documented, and shouldn't need significant support in this context. But it has never been rewritten to accommodate the more recent LOOP2 instruction. So any software that utilises LOOP2 will fail with the current version of VVP and that can't change until a complete update or rewrite of VVP is undertaken, which isn't on the horizon at present.
Let's hope that his circumstances improve and that he returns to and can make more progress with VVP2 at some point in the future.
