The issue you're facing seems not related to this PR at all, but it's about extranonce_size requested:

@GitGab19 seems to be working but I have no idea how d530cbc would really need some sanity checks here and to ensure it's not just wrapped around this specific use-case.

I think it's a garbage solution but can probably help us understand the issue better. The JDC adds a 2-byte routing prefix; for a pool limit of 4, enter 2.

"The original issue was a hidden JDC default.
The UI showed Extranonce2 as 4, but jdc.toml omitted:
reserved_downstream_rollable_extranonce_size
The JDC therefore defaulted the reservation to 8 and added its own two-byte routing prefix:
2 + max(8, 4) = 10
CK supports a minimum request of 4, so it rejected the hidden request of 10 with unsupported-min-extranonce-size.
We fixed it by generating:
downstream_extranonce2_size = 2
reserved_downstream_rollable_extranonce_size = 2
Now the JDC requests:
2 + max(2, 2) = 4
CK accepts that. The later miner socket disconnect is separate from the original CK/JDC configuration problem."

makes no sense to me

I'm reporting here that running this PR allows me to mine on CKPool. I however don't understand all the changes done here as it seems there was a structural bug in how we do configs.
