bug#47749: Feature Request: Make top/htop give usable readings for the packages

[bo0od]

Hi There,

Using top/htop is helpful to know many info like running packages,memory 
usage...etc

But in guix the problem with any running service it show long path 
/gnu/store/pathxxx/packagename this is not useful as the name of the 
package will be hidden from screen due to its long name. (some 
workaround can be done but its usability disaster)

Can guix give readings to just the package name running without the need 
to mention its path?

check the uploaded images.

ThX!
