I think that's a bit of an exaggeration; "pull.rebase=true" should be fine as long as you don't have local merge commits that need to be rebased on top of someone else's changes. With ordinary commits, it shouldn't really matter how frequently you (or others) push.
"git rebase" has --preserve-merges (apparently renamed to --rebase-merges a few years ago) to recreate those local merge commits, maybe it can be set somehow for this as well?
