I've noticed the same - I think I would prefer to have the option to enable/disable it as the level of "bridging assistance" I need does vary with filament type.

Agreed. The only time I really need this slowdown in my prints is in cases of very low infill...such as <10% honeycomb.

Likewise. I have a setup where the fan is used for both hotend and filament cooling, and bridge speed works great for short periods, but for long periods it clogs the nozzle. Given that it really does not seem necessary (at least when infill is dense enough), I would be in favor of adding an option for this behavior.

I use to add some M220 S200 at the beginin of my prints to over-ride this...
... But sometimes forget to get normal speed after first layers been printed )-:
Will be great to have the ability to chose what we need, when we need it !

Yeah, I can see where this would be useful (especially if you know your machine very well), and it looks straightforward to implement. I'll have a branch + pull request up shortly if someone wants to give a hand testing :)

I'll have the configuration default to 100% (which is the current trigger for not doing bridging infill).

Hm, I had actually addressed this issue in 38a9e32 (after this issue report). And I have one more improvement for making this logic even stricter.
