remove implication knot_in_sheath (1856) -> knot (216667)

Reason: Looking at bulge and penis outline their wikis state that since the penis/sheath/balls are not directly visible, those tags should not be added.
Knot in sheath does the exact opposite by implicating knot even though in most cases it is also not directly visible, only showing a bulge instead.

Didn't find any forum posts really discussing this so here we go. Should this be unimplicated or can a knot be tagged when not directly visible such as bulges/outlines?

Both of your BURs rely on whether or knot you can have a knot adjacent tag without a knot visible, if the situation heavily implies the knot adjacent tag. (For example, can a bulge where the knot would be imply stuck knot)

In this case however, either knot in sheath should not imply knot, or the wiki for it should be changed, since it states

knot in sheath:
...The knot can be indicated by a large bulge in the sheath...

which doesn't require a knot to be visible.
