Regular users and those who sympathise with them normally try to avoid driving on wet roads if it will obviously do significant damage and the trip is not an important priority.  It can be very annoying to those trying to avoid damaging the road  when "urban cowboys" trying out their 4wd's effectively deliberately plough them up.  
These types would most likely not be obliged to use the road again in the condition they left it.  Including when it had dried to various extents leaving very deep and hard ruts that are very rough and often difficult to drive through. I got stuck once in near dry ruts on a back road near home when most of vehicle weight was on diffs scraping the ground.   Also, is a lot of not easy work grading the road.  Often take several runs to properly fill in and smooth out the ruts.  A bloke I know told me about an incident in Queensland.  A group of "urban cowboys" that had just made an awful mess driving up and down a section of muddy rural road was confronted by a representative of the local Shire backed by police who presented them with a large bill to cover the cost of grading etc to repair damage they had done.  
I have heard of cases where 4WDers have become bogged doing stupid things that have unnecessarily damaged the road and locals, including rangers in forests passing by have left them there, despite being fully equipped to pull them out.  However, the same people would almost always help those who got stuck while trying not to.  With this approach, would sometimes cost idiots a lot of time and money arranging to get out if no mates nearby.  
When there is a wet boggy patch on an otherwise easily passable road, sometimes a detour can be made around it to avoid making the bog worse and maybe leaving less mud to clean off vehicle.  Responsible road users who have good reason to go through usually try to minimise the destructive effect.  
Those who want to test 4wd's in the mud should try to find places where damage done is least likely to upset anyone.  eg a track which was formerly a road and has been replaced by a new much better road  nearby serving the same purpose better. 
Note I am a farmer who drives a Defender.  Find its capabilities handy despite largely deliberately trying to avoid mudholes with it.
