It is interesting that you say that. This is fact already exists. An unbundled version of electron, that can be used by multiple applications, is called a web browser. Applications using it are called websites (or PWAs if you must)

Unfortunately, certain applications are gimped if you don't use the electron version. A notable example of this for me is Discord where push-to-talk doesn't function in the web version due to API limitations.

Another app I use that has this problem is Spotify. While it isn't electron, it is using CEF (chromium embedded framework) and can be dynamically linked to a distro one with some effort. Using the web version means I dont have my music available offline for listening.
