AW: Why doesn't Ideographic (ID) in UAX#14 have half-width katakana?

No. They are still in use.

One typical usage of half-width kanas is the display of short texts on small devices of embedded systems, like status messages of control units,
for example a one-line display, 30 characters wide, monospace, with 8x10 pixels per character.

(...)

AFAIK, the existence of half-width kanas in Unicode is
purely for backwards and round-trip compatibility.
