There was actually a patreon poll where the dev had asked this same question about the size of updates:
You must be registered to see the links
If you cannot access it the relevant contents are as follows:
"Also, 0.5 will have the amount of content as the previous updates (a big one), but I wanted to use the occasion to make sure that my release schedule is to your liking. I can't work faster (nor slower! ), but I can continue releasing big updates as usual, or release smaller ones (less content, but more frequent)."
The post has 1,533 votes total with 95% voting for bigger updates + longer wait time vs 5% voting for small updates shorter development time. Given the overwhelming majority of votes went towards larger updates, it is not going to change. Usually it looks like the dev time is around 4 months. This update has taken a bit longer than usual but that is understandable in my opinion given it is holiday season.
