The way I use the Replay feature is to work through changes to my Jenkinsfile without committing a bunch of intermediate changes that may or may not work.
I think the best way to "improve" this would be to add the parameters to the top of the replay page, as if I had clicked "build with parameters".
I thought a workaround might be to go into the configuration of that pipeline and either delete the parameter or change its value. In my case, the pipeline is part of a multibranch pipeline and doesn't allow me to save changes to the pipeline.
If this isn't a feature, there should at least be a workaround...
