It is a burden on bots, on GH Actions we run, on people who actually maintain it, on users who try going this route without thinking. Spin it out into an alternative to Conda if you so inclined. Such a separation would make it clean for the user that it is not necessary in 99% of the cases, that it can be updated independently, etc. I should have added the rest of Sage “toolchain” to the list. > It's -1 from my side unless: > - there is a tool that allows installling gcc (or a tested compiler) > without root privileges, > - it's well-documented and whatever the instructions, also a non-advanced > person can follow it, > - there is still support for the issues with that (it doesn't have to be > from our community) > > In general, I think it is a good idea to join forces.
