As far as I read on LKML... breaking userspace is a reason not to do
such changes.
That's really a reason not to break "handmade" scripts on some machines?
As this is new to me... is that documented?
Surely, it's fretful to change scripts, but life is change.
For me there is a more reasonable thing... Did you grep for "option"
pattern in the kernel sources?
Try.... :-).

Hmm, being a non-English native, I am not sure to get this...
What about languages from mostly Eastern countries having so much
consonants in a single word like Russian, Polish, etc.
Not every language is rich like German which has WOWels like "ä" (ae)
"ö" (oe) "ü" (ue).
