Publishing a framework review
I think that there are two questions in here that it may be useful to separate out:


Should you spend the time to prepare a well-written analysis that you make publicly available to others?
Should you make your analysis available in the form of a peer-reviewed paper?


For the first, it seems that you've done much of the analytical work already, and that there are people who will appreciate it.  I thus see no reason not to produce a good write-up and publish it.  

Whether you should publish it as a peer-reviewed paper, on the other hand, is not so clear to me.  I don't think that you need to worry about being looked down upon for publishing such a paper: that concern is more about bad work, not work with a clear, intentionally limited scope.  I just don't think there's much to gain from going through a formal peer review process here unless your work involved more experimentation and surprises than it sounds like it did.

Instead, I would recommend posting your analysis as a technical memo (many institutions have a mechanism of this sort), a whitepaper, an arXiv pre-print, or other such semi-formal document.  A semi-formal publication of this sort can place your work in a permanent archive with a DOI and clear means of citing if people find it useful, yet also is fast, easy, and need not be a significant distraction from the main thrust of your research.
