Why does slicer default to "Don’t support bridges"?

There may be a reason, but why does Prusa Slicer default to "Don’t support bridges" after installation. I can only think of a few situations where this would be beneficial, and many more situations where this would result in failed prints. Would it be sensible to have this default setting reversed in future versions?

Best Answer by Neophyl:

Most bridges will print fine without support.  That's the whole idea of bridging after all.  Prusa generally do not like to alter defaults of profiles if they can avoid it as it causes complaints.  Especially with the Dependency system used for them.  Imagine thousands of people who silently and unknown to them had a setting in their profiles change on them.  That is exactly what can happen if you use the defaults and don't save your own copies.  

If you want to support  bridges then just untick that option and save your profile as your own then use it from now on.  

What PS could do with is a Maximum bridge length setting (which has been requested over on the PS github).

I think this really depends on your situation. I make a lot of models that have small bridging areas, and getting supports out of them would be a real pain. In either case, it's a simple act of checking or un-checking the box and saving your preferred profile. As Neophyl pointed out, a "Max Bridging Distance" would be a nice option to have.
