Of course you can propose it. However, it should be rejected. What you have written could be the beginning of a great tag wiki — but at the moment you seem to propose it being in the excerpt (which is where your original quote is).
Tag wiki excerpts should not define the topic unless it can be reasonably assumed that most people don’t know it. They should ...
I agree that it should be removed. I was the one who created the nitro-compounds tag and the wiki to go with it. I wasn't aware that MathJax didn't render in the excerpt popup but if I was then I wouldn't have used it. It doesn't seem essential to convey the meaning; it just makes it look a bit nicer.
Vote this answer up if you think we should also include other types of esters in the ester's scope.
We're being consistent and scientifically more accurate.
This might lead to further confusions. For instance, how should we tag this question? It already has nitro-compounds which, IMHO, sufficiently covers the indication of ...
Okay, let's look at the results after 47 hours and 52 minutes & 37 seconds and 937 milliseconds 1:
Inclusion of all esters in ester: 5 upboats
Inclusion of carboxylate esters only: 1 upboat 1

Vote this answer up if you think we should only include carboxylate esters in the tag.
Avoid confusion: The majority of the questions on the site are about carboxylate esters anyway.
Avoid possible tag broadness: Every tag scope enlargement is followed by an inclusion of a set of specific questions. They might make the tag overly broad (which ...
