I said the idea was OK :-)  I forgot that Eglot's own display of
the project name is not only that.  It has more functionality:
the project name is only a label.  So what I thought would be a mere
replacement and is actually not.

It's best to allow the user to choose, and Eglot doesn't have a way
to let the user choose (while project has). So let's give them one
in Eglot.
