One of the fun parts of chemistry is that most chemicals that ordinarily exist are quite far from having the most extreme possible properties that you can ascribe to a chemical. It doesn’t really matter what the property is. This is almost by definition, as “extreme properties” is roughly a synonym for “extremely unfavorable thermodynamics”.
Nonetheless, chemists are obsessed with these because in theory you can engineer chemicals with completely implausible, or at the very least counter-intuitive, properties in a lab if you can figure out how to do it. It is the equivalent of extreme performance-engineering geekery in software. You do it because you can, not necessarily because you have a use case.
Topics like “theoretical limits of high explosive power” [0] and a lot of other things that will put you on a government list are something chemists definitely geek out on.
