Thanks for the source which gives the full
names of the three time zones.
The decree of 1963 probably has established the
three time zones with UTC + 07 h, UTC + 08 h,
and UTC + 09 h. Before that time, the names
Waktu Indonesia Barat and Waktu Indonesia Tengah
would have made little sense because both
regions used UTC + 07:30 h.
My point, however, was not the proleptic use of
WITA in itself but only its unsystematic
consequence in the proposed change to tzdb:
from 1948-05 until 1950-05, all three time
scales of Asia/Jakarta, Asia/Pontianak, and
Asia/Makassar agree with UTC + 08 h; but the
tzdb abbreviations are different: two use
+08, and one uses WITA.
This is unlikely to reflect local practice.
