In the question Geometric interpretations of matrix inverses I have replaced the deprecated tag with . Is it a reasonable choice? What other tags would be suitable? The questions does not have a top-level tag, although is "close to top-level".
Q: Geometric interpretations of matrix inverses

user21816$A$ is an invertible $n \times n$ matrix. Interpret each row of $A$ as a point in $\mathbb{R}^n$; then these $n$ points define a unique hyperplane in $\mathbb{R}^n$ that passes through each point (this hyperplane does not intersect the origin). Under this geometric interpretation, $A^{-1}$ has ...

I have added also . I am aware that the removal of the tag has been discussed on meta. But at the moment the tag still exists, so in case the final decision will be to keep the tag, it's easier to added it now that question was bumped. (A tag can be removed without bumping any questions.)
A: Help cleanup tags!

Federico PoloniThe tags matrix-analysis (32 questions tagged) and matrix-theory (18 questions) should probably be merged, unless there is a strong difference between them that I am not aware of (incidentally, there is also matrices, 150 questions tagged). The tag matrix-inverse (6 questions) seems overly speci...

BTW the tag has now 70 question. It had 6 questions when Federico Poloni made the linked post.
