God I'm a right miserable sod but I honestly can't see a home system being of much relevance.
The system thing just seems to be a mechanism for Frontier to push groups into fighting over territory, in that if it's your own group you'll be more invested that fighting for them rather than <insert random pp figure here>.
Tech level, what outfitting it has, I don't see as being important, it's unlikely anyone is going to be "based" there, nor or is likely we will be defending if some other power decides they want to take over, we are not the type of group that's going to be tied to a system. Talking about we must have this or that means nothing because people meet where ever is most convenient, and log in and log off where ever. If it doesn't have a black market or an outpost, in the end so what? It's something to talk about I suppose but in reality it's a total non-issue.
We could say tomorrow, our home system is Beta Sculptoris, but it wouldn't mean anything. I would not be any more likely to visit there unless something interesting happened like a bunch of UAs were spotted.
It would be nice to have a system that's interesting lore-wise attached to the Canonn name but beyond that I don't see the point of it except that Frontier says every group needs to pick one.
