Lua has been known to remove things. The language still remains small and clean after over 20 years. The creator has given some talks about how breaking compatibility (e.g removing features) requires its own thought process. There are different types of changes. The easiest to change are the ones that can be detected immediately in existing real world programs whereas the hard changes are the kinds that could go silently undetected by users until it is too late.
