   Some upstream maintainers started pulling it as a dependency, in    
   order to not have to condition their code to emacs versions, while    
   also using the latest functions provided by the most recent emacs.    
   This library made sense to them insofar as it allowed them not to    
   have to update their code down the line.   
      
   Since the upstream maintainers of some third-party elisp libraries    
   started using it as a dependency, we had to package it to package    
   those libraries as well.

   Now, since a stub version of compat is included in emacs since    
   version 30, compat is only going to be useful to us if :   
   - a new function appears in the 31 branch.   
   - AND the maintainer of compat decides to implement it, and    
     release some version of compat 31.x.x.x.   
   - AND some third-party elisp maintainer (of a package we package    
     in debian) decides to pull this compat 31.x.x.x version as    
     dependency in order to use this brand new function.   
      
   If this happens and we have removed compat, we will have to wait    
   for emacs 31 to be released (and packaged by us) to be able to    
   package this new version of the third party elisp library.   
      
   I am not sure how likely this situation is, and whether this is    
   really a problem : we could perfectly decide to delay packaging a    
   new version of a third-party elisp library until after the needed    
   emacs version is released by upstream and packaged.   
      
   Best,
