use ByteString instead of Text for regexes?

[legrostdg]

I'm trying to package goldplate in Debian. I've an issue with regex-pcre-builtin, which is not packaged (and, from what I understood, not wanted) in Debian. regex-pcre is already packaged, but it does not seem to have Text.Regex.PCRE.Text. Is there a reason why Text are used in src/Text/Regex/PCRE/Simple.hs, and not Bytestring? It would help packaging a lot if I could use regex-pcre instead of regex-pcre-builtin...
