I've got no idea how many of the current 2561 products on GOG catalogue are "base games" (i.e. not DLCs). Within Legacy MaGog's scope, 1768 out of 2171 catalogue entries are "base games": that's a 81.4%. Assuming the percentage of non-DLCs has remained the same since MaGog stopped tracking GOG products, the number of "base games" must be somewhere around 2086.
That means that there are still about 2086 - 439 = 1647 potential "internal installer updates" remaining.
