All those tools are included in Nuendo, as well as in the TC PowerCore
package: multichannel dynamics, EQ reverb, delays, etc. But none are

As far as I know, though, the big mastering studios continue to perform
their work based on stereo techniques: they monitor the front channels
separately, process them, then route only the surround channels to the
front speakers, and process. The surround monitoring is only used for
final check.

If the music industry continues on its current trend, which is to mix
in surround using the movie industry audio standards (minimal
compression, big headroom, standardized monitoring levels, etc.), the
use for multichannel compression will be much less critical than it was
in the past few years with stereo mixing. EQ also is less needed at the
mixing stage, because "unstackable" elements can be easily routed to
other channels.

For the LFE channel, I never heard of anything specific... except that
this channel is very seldom used in music mixing, for compatibility
reasons: the huge majority of home systems only have a general purpose
