That's exactly what they do when they publish results in the NCAA and at USATF nationals, and when they display marks on their fancy digital boards by the field events at many college meets, they show both. Have you been to a college meet lately or looked at the results? They already do exactly what you are asking for. You can look at the USATF results from Indoor Nationals that finished yesterday, they published the field event results in imperial and metric, in fact looking at the videos and pictures from the meet, it looks like they displayed field event results on digital boards that had metric and imperial measurements in real time, so I don't think you can blame USATF for "trying to kill the sport" at least in this one case:
https://results.usatf.org/Every article and results that USATF publishes uses both metric and imperial, here's one from Friday:
https://www.usatf.org/news/2020/american-record-breaking-triple-jumps-highlight-daLooks like we have a new national record in the women's triple jump of 14.64 meters or 48' 1/2".
So what is it exactly that you are complaining about?
Are you upset that people keep posting Mondo's new pole vault records on this board in metric? Those marks were set and published in Europe, there's no reason for them to publish them in both metric and imperial. Why should posters have to do the conversion for people like you? Take the 5 seconds to do it yourself, or here I'll do it for you real quick:

It would take you less time than the time you've spent complaining about this so far.
Where people like you are eventually going to suffer is at places like high school meets, because when they start measuring and recording metric marks, they will be calling out the marks in metric, and you'll have to sit there and convert it in your head until you get used to the new measurements. Sure once the results are published they can easily display both, but if you want to follow an event in real time you'll eventually have to get comfortable.
But lets be honest, you don't go to meets and you don't follow field event results. If you did this would be a non-issue for you.
