I disagree that it shouldn't have been enabled globally. There are probably thousands of optional features and preferences in an operating system, yet few users know of them, and fewer care. Although, I do agree that more interface tools would be helpful. However, the "normal" way of creating these infoboxes requires considerable trial and error and expertise that veteran wiki users take for granted.

Just as a simple example, to make a basic infobox using the old approach, you need to know wiki markup for tables, images, and  links, basic CSS knowledge of inline styling, and some knowledge of template markup, and mostly importantly a lot of crazy wikitext quirks.

Some users take that for granted, but I'm 100% sure that there isn't a single user except maybe the developers who created that markup that will get all of that right on the first few tries. Yet now it is possible to create a portable infobox on the very first try. As far as making it optional, I'd suggest using C for that.

Given that the source mode is still accessible, there is basically no disadvantage of keeping it as the default. Especially because currently it fails to load for templates created before the builder was introduced (as far as I know).
