I see no reason why we can't keep producing CC1 sets, however I do think that CCLP4 should be the end of the line for the traditional 149-level CCLPx format. Going forward, I feel like we would be better off producing smaller CC1 packs (maybe 75 levels?), more focused packs (like a "veteran pack" or another MS-only pack) or other kinds of new formats that would still allow us to publish official packs of CC1 levels without taking the focus off CC2 official packs, which should probably be the new standard going forward.
My big thought in saying that is that a bunch of modern CC1 levels can be ported to CC2 (either directly or with minor modifications, and even with the contrasting boot drop rules) and I would rather put the best we have to offer into CC2 packs if we can, as CC2 is the future of Chip's Challenge; a high quality CC2 pack could do a lot to lure people into the community who would otherwise simply play the main pack, say "ehhh, it was okay I guess", and leave to play other games.
