Maverick thanks for the comment about the sensors. I forgot about them. The wider canopies on some jetways just get in the way of sensors antennas etc. Some jetway canopies are also not rolled over on CRJ's because of the roof antenna in proximity. The simple ground level RJ gates at Montreal Dorval on the end of the transborder wing for example had to be reworked so they wouldn't knock off the antennas.

Interestingly enough, the reason for the hood isn't only for keeping the weather out but there's a safety aspect with respect to fire. IIRC the hood is designed to provide 5 minutes-ish of fire protection before burning through.
