BUR #2408 has been rejected.
remove implication held_down -> restrained
remove implication stationary_restraints -> restrained
mass update held_down restrained -bound -> -restrained
create alias restrained -> bound
create implication stationary_restraints -> bound
Reason: The distinction between bound and restrained should be made clear; failing that they should be merged.
For example, we might say that bound entails artificial means (chains, ropes, bars etc.) while restrained entails natural (held down) or quasi-natural (tentacles). Or, we could say bound is a subset of restrained (so bound implies restrained), where the restraint is achieved through artifical means.
EDIT: The bulk update request #2408 (forum #164516) has been rejected by @Arcana55.
