Do you consider a huge overhead a lookup in a array, checking if string
need to be processed and process it only if necessary?
I don't.

Most collations do simple operations now. With UTF8 strings the overhead
will be transfered to collation functions.

The argument about that the codebase will be more simple is true with
the current codebase, but with a maintanable codebase the complexity is
not high.
