Both ways are useful: single pixel decompression for texture sampling, whole block for whole image conversions.

FWIW, I don't see any new s3tc formats. rgtc will not be handled by s3tc library since it isn't patent encumbered. util_format_is_s3tc will not include rgtc formats. (Though I guess that external decoding per-pixel is really rather lame, should do it per-block...)
