Comment (by barry.wardell):
Yes, when I was testing it, I found that it actually slowed !McLachlan down a bit, but did give a speedup for !WeylScal4. This was before a lot of the recent speed improvements in !McLachlan so it would be worth checking again. I don't think we should just blindly enable it, though.
The benefits of CSE might also depend on e.g. whether Jacobians are enabled or not, how aggressive the CSE is (this can be tuned), etc.
