Why to music producers not bother with CD-TEXT I still like CDs, buy one from a shop and slip it into my car, easy - no encoding, file transfers etc etc...

CD-TEXT has been around for a LONG time, but I have only ever come across 1 or 2 albums / singles where the producer bothers to put the CD-TEXT data on the disk. 
Given that it is a simple, open and free thing to do, and nearly all CD players (home and car) support displaying of CD-TEXT data, why is it not more widely used?
The only answers I could quickly find are that they either don't think about it, don't want to have to deal with clients that supplied incorrect track information, have a duplication house who's software can't support it (apparently there are some errors in one of the major pieces of software used by duplication companies) or think that the CD-TEXT data can result in a slightly slower cue time on the CD.
