I think it is a fair compromise if the board is as original as possible with socketed parts that are readily available and easy to replace. 9602 are hard to track down, 5101 are expensive (if you can find them) and 6800 supply will run out. Even tracking down 2716 / 2732 can be difficult and expensive.

I'm really loooking forward to the release of whatever format is feasable, cost effective and supported. This is great news for people like myself that enjoy restoring machines in this format.
