MTU for channel 0 ， is soooooooooo big

[sgyli7]

As in your code :FishNet/Plugins/FishySteamworks/FishySteamworks.cs
private void CreateChannelData()
{
_mtus = new int[2]
{
1048576,
1200
};
}

which the channel 0 MTU is soooooo big, far more than normally 1200 . I think it would only support LAN . For weak network environment, i think it may cost message blocking.
Is there any reason for this design ？

Recenly ， I always receive Steam 's error log :
Could not send: k_EResultLimitExceeded. Event I change the window size to VertLarge (1.5M)
