Changes between Initial Version and Version 1 of Ticket #10142, comment 109

initial	v1
3	3
4	4	It's a little thing, but I do so hope we'd go with `term_id` instead of `term_taxonomy_id`; my fingers object in a passive aggressive manner every time I try to type the latter; they inject typos into that long identifier name. :-)
	5
	6	> - We'll need CRUD wrappers for `add_metadata()`, `update_metadata()`, etc.
	7
	8	What's the chance of revisiting the idea of a more generic meta_data table that would allow for other types of metadata in addition to metadata for term/taxonomy? I'm not suggesting we change post, user or comment meta but that we consider term meta being just meta with an `object_type` field?
