There are a couple of threads on forum where people have bypassed clutch switch because of faulty switch and had problems with engine cutting out when slowing down, they had to get another switch fitted and back in circuit to cure the cutting out, clutch switch is connected to ECU and plays a more important purpose than just stopping engine starting if in gear.. will try and find threads and post a link.

Found it - there is a link to thread in this forum and also one to svrider.com ( USA SV sight ) - quote from svrider site

'The clutch switch is used to enrich the fuel mixture a little when the engine is decelerating (which is normally a high vacuum condition with the engine
speed high and the throttle closed) with the clutch pulled in. Otherwise, it can stall. If you bypassed the clutch switch, the ECU won't know you pulled the
clutch in and let off the throttle, so the engine rotational speed will fall faster than ideal and can stall'.
