He means that text won't work with 6.10 *if* it's changed to use the conversion routines that only exist in 6.12+ as you seem to be demanding.
Exactly. But it is probably possible to make version of text which with 6.10 uses some copy of the routines and with 6.12 uses the routines in base. The compatibility issue is only temporary i.e. until there are many users of 6.10. The API from text will have to stay forever. For now at least the API should be made compatible with base. For example something like that: encode :: TextEncoding -> Text -> ByteString decode :: TextEncoding -> ByteString -> Text where TextEncoding could be defined in the text package when it is compiled with GHC 6.10 or just reexported from base when it is compiled with GHC 6.12.
