And thank you for it!  If this is where Guix ends up when left 
unattended, it should be fixed.

Easy to do by making the ‘old generations’ submenu a separate file 
that's loaded ‘on demand’.  Actually doing so would still take as 
long, so the next logical step is to split it further into chunks. 
How, I guess, depends on how people actually use & browse 
thousands of generations.  Do you?

Kind regards,
