In reader conditionals take :bb OR :clj branch (in that order)

[borkdude]

Libraries like regal work just fine with babashka, but because they have no explicit :bb branch in their reader conditionals, many functions just return nil. Instead, babashka could just take the first :bb OR :clj branch with a priority for :bb. Still we have no guarantee that the library maintainer is willing to check compatibility with bb for future versions unless they explicitly state it, so it might always make sense to fork and curate these libs.
