Thanks for your interest, the scissors are interesting but when they were removed they were replaced by single crossovers and not removed completely. Therefore, all movements involving the crossings can then still be done, if not as efficiently as before! (Involving, say, reversing rather than straight running over the crossovers)
The vast majority of photo evidence we have, for our intended period, shows just the single crossovers. The signalling for these is much more visually attractive than with the scissors in place as a lot of the signals for those were hidden below the station canopies, so the mood of our group (maybe) is to have the crossovers as single.
