Although I don't have a concrete proposals myself, I agree that
without having any common notion of what the "minimal target hardware"
looks like, it is very difficult to discuss other things that depend
on that.
If there's data that shows that a 100 usd raspberry pi with a 1 MB
connection in say, India (I actually have no idea about internet
speeds there) size X is a viable full node, then I don't think anybody
can reasonably oppose to rising the block size to X, and such a
hardfork can perfectly be uncontroversial.
I'm exaggerating ultra-low specifications, but it's just an example to
illustrate your point.
There was a thread about formalizing such "minimum hardware
requirements", but I think the discussion simply finished there:
- Let's do this
- Yeah, let's do it
- +1, let's have concrete values, I generally agree.
