MaxActiveOutboundChannels: PlainDescriptor<number>

Maximal number of outbound XCMP channels that can have messages queued at the same time.

If this is reached, then no further messages can be sent to channels that do not yet have a message queued. This should be set to the expected maximum of outbound channels which is determined by [Self::ChannelInfo]. It is important to set this large enough, since otherwise the congestion control protocol will not work as intended and messages may be dropped. This value increases the PoV and should therefore not be picked too high. Governance needs to pay attention to not open more channels than this value.
