 dimensional arrays, then OK.

 I don't believe it will be an issue unless you believe calling `in_array`
 for each value in a one-dimensional array will cause significant
 performance loss. The other option is to to check something like
 `$is_multi = is_array( array_values( $l10n1 )[0] )`, but to determine
 which was more performant would def. require some benchmarks. I would not
 be a bit surprised if multi-dimensional arrays were often used.
