See this thread from a few years back.
I may be such a complicated person, but somehow if you managed to obtain a written permission to persuade the related governmental entity to allow explicit import from data.gov.my into OSM - then you totally have got my support to begin any work on this import. I’ve done so a few years ago, but I didn’t get a (definite) reply from their side.
Otherwise, these lists are fine. Use them as a guide, and independently ground truth bit by bit a la geocaching. But definitely no straight up simply copy paste here and there.
