A few have already done it, as you can see above, but I haven't done it. Yes they run hot but the advice I have been given is that as long as you keep changing the oil and filters regularly (after two rounds, except Snett which I'll have fresh oil and filter for and after) you'll be ok.
If you want the extra peace of mind I don't think you'll lose anything by fitting it. It's up to you really.
