Restart requried for config changes via Spring.SetConfig*

[gajop]

Is it an error that some config changes done via Spring.SetConfig* functions don't take immediate effect?

I've noticed that link bandwidth (LinkIncomingMaxPacketRate, LinkIncomingMaxWaitingPackets, LinkIncomingPeakBandwidth, etc.) value changes require a restart, but I'm pretty sure some others don't, yet this probably isn't documented anywhere.

Should it be documented or rather changed so that all config changes take immediate effect?

Some need a restart, some can be put into an "overlay" and applied instantly but not remembered, and some cannot be changed ingame at all. I didn't find a way to tell which is which other than time consuming code reading.
