Iirc, even the texbook says something along the lines of 'you are lucky if it works'. The argument to keep it seems to be that even though it is  a truly weird idea, it has been in use for a long time, so it should be kept forever. To me, that is far from convincing.

The reasoning stems from the encoding mess. The %! line can specify
the TCX table to be used for processing the file. While it may help,
it may also be a source of confusion. For instance, I use UTF-8
locale. If I get the file by email with proper locale set in the
sender's mail client, and I save it, my mail client will always
convert it to UTF-8. If the original file encoding were different, the
information in the %! will be wrong. IMHO this concept does not help
portability unless you pay special attention when sharing files.
