How to handle works with several versions with different visuals?

Sorry if this has been addressed somewhere already, but I found these works as good examples to illustrate this question. So what we have here is a work that has a "regular" as well as a version that is stripped down to just box visuals. And then we have a work where the visuals have been improved between uploads. In both cases the audios have stayed the same.

While I saw this second case as something where these two uploads were visually similar enough that they could be bundled together under the same Work with a caveat, how about the first case? Should the regular version and the box visuals version be treated as separate works or could they be bundled together as well, since they technically represent the same project/audio and are from the same user? I know there are other similar cases out there, so this should help give some clarity when this comes up again.

In both of these scenarios I believe they should be collected under a single work. The has revision tag is seemingly being used in the case of an update for an otherwise finished work. There should probably be a similar tag made for works with just box visuals (work #9790 and work #19440 come to mind for this). In this case we should be careful what we name the tag, since something like "box visuals" would imply the entire work is like that, however in these cases it's simply an alternate version. "has box visuals" is a potential option.
A case I'm uncertain about, are works where originally they were uploaded as audio only, but a later version added visuals. work #10645 is an example of where they're currently under the same work, but work #12612 and work #12700 is a case where they are separated (though hold a Sequel relationship). You could also consider a "full version" to be relevant to this scenario, but so far I believe these have all been categorized as a separate work and related to as a sequel, which seems correct to me.
