There is a precedent.

The behaviour of table.insert and table.remove in the case of
an invalid index, like the previous empty match behaviour in
gsub and gmatch,

1. ... used to be undefined but reproducible.
2. ... every now and then was the subject of a new post by
   someone who thought that it was unintuitive, and annoyed
   the Lua team [1],[2] by branding it as a bug.
3. ... was changed in a "bugfixing" release to be no longer
   undefined.
