All of this doesn't work on macOS BigSur. Only the user who installed all the Homebrew stuff is able to upgrade them afterwards. For all the other users the system complains with Operation not permitted since th folder belongs to the other user. It seems like Homebrew does not respect the groups write permission and only looks for the user... :(

@Blackjacx I am on Big Sur and this is mostly working for me, but I have to reset permissions every now and then after upgrading.

It seems that this method might be better, any reason it may be less desirable?:
