Sankaku Channel/Help & Documentation Issues

Hello!
There is an undocumented feature in the tag edit form that I'm looking to clarify: the parent and child fields. The function of these fields, in addition to being unexplained in the wiki, is unclear throughout its use, as well as on the surface.
Through a deeper look, I've observed that what these tag edit fields do is to publish parent/child information to the tag's wiki page. As ALAKTORN and I have discussed in another thread, this category of information has an unclear purpose. For example, Is this parent/child information supposed to reflect the tag's implications? Because if so, these parent/child fields could be eliminated entirely by instead pulling implication info automatically from the database.

EDIT: What is the real purpose of the parent/child sections in a tag's wiki page, and of needing to edit them from the tag edit form? Is this feature worth keeping as is? If so, how should it be documented?

^Maybe I should’ve mentioned it earlier, but there’s a topic for tag relationships: https://chan.sankakucomplex.com/forum/show/1386

I'm sensing a suggestion to post it there. This is just as much a general feature question as a documentation question after all. =)

EDIT: Wow, taking a look at that topic, the tag relationship system is deeper than I thought! Looks like I have some learning to do first.
