It has only been a few days since we declared plot-inconsistency as a synonym of plot-explanation, because it added no value at all:
Should plot-inconsistency be scrapped in favour of plot-explanation? [**VOTING CLOSED**]
Deeper discussion: Let's nuke [plot-inconsistency]!
Now there is already a new contestant to replace this useless tag since it has become unavailable.
This question was tagged movie-mistakes by the user. In fact it is however asking for an explanation of a plot point, so I retagged it as plot-explanation.
I am afraid people will just use movie-mistakes now that plot-inconsistency is gone, which undermines the very goal we were trying to reach by removing that tag.
There is exactly one question under that tag, which asks about a verified movie mistake and where to find it:
In which scene is the White Van in Braveheart?
I can see how the tag makes sense in this case, because the user is not asking if something is a mistake, but asking a valid question about the mistake itself.
However, it is only one question so far and the tag has a high potential for abusing it as a replacement for tag-inconsistency. I created a tag wiki that tries to discourage users from using it that way, but the question arises:
Do we need movie-mistakes at all and is the abuse risk worth the very few questions that fall under that category?
The one question that uses it could probably be retagged, for example with production.
