After reviewing the code it appears we do allow both - and _ specifically so I'll need to update the part that parses the variable names to accept -. I will post the pull request link here once addressed.
CORRECTION:
After looking online for a split second I remembered the reason why we don't allow -. In MySQL it's not acceptable to use dashes in column names. Since we use the variable names as the column names in the respective CDATA table we simply cannot allow dashes. So I will instead need to remove the - from the validator so it fails if dashes are present.
Cheers.
