Sure but that's not really helpful, the only thing it does is avoid breaking history visualisation tools which tend to deal very badly with "wide" histories.

For instance one of the biggest annoyances with git is it's a pain in the ass to find the the merge of a commit into the mainline (aka the next child with more than one ancestor… probably), which can make it difficult to go back from a commit to a PR unless it was a single-commit pull request.
