I hate all the cruft in my home directory, but I also hate when stuff suddently stop working after an update, or when all the documentation online talks about something that doesn’t work on my system or is not there anymore. Developers are the ones that will have to deal with people with these issues, so I can see why they are reluctant to implement the naive solutions that some ask for.

What you need here is not the stability in memory (i.e. of pointers, which you lose when you recreate an object) but instead just the stability of an identifier (e.g. the index into a list).
