We previously allowed 250 parallel incoming connections from nodes with whom we don't have any channels yet. While this makes sense for wallet providers, this is too large for standard routing nodes and exposes them to more DoS risk. We reduce the default value to 64 instead, which can of course be overridden by node operators in their `eclair.conf`.
