As a result the Bash fallback logic masks an incompatibility between the

namespace of the local system.

However, the bash work around is going to be removed[2].

This was removed in bash-5.3, the current version. That may not make as big
a difference as you think -- some Linux distributions still ship with
bash-4.2 -- but it will become more common over time.
