It sounds bad for cyclists, but it might be good for the environment if it means rights of way can be made to disappear after their original purpose is completed. If logging roads would cease to exist, once logging is concluded, that might be a good thing.
Rudi, sustainable logging can be a good thing. Wild life thrives where loggers have cleared part of the forest and sunlight can then reach the ground. Trek through a forest with a thick canopy and you rarely see any wildlife let alone plant life. In all things balance is good.
