Why are you thinking only about changes related to how the project's name is
spelled out?  What if someone would like to make changes in Eglot's
mode-line indication that have nothing to do with the part of project name?

You see this as a request to customize project.el for some reason, whereas I
see this as a request to customize eglot.el, because the mode-line indicator
is produced by Eglot, and the fact that it currently shows the project name
in some form is not carved in stone.
