I don't. Should I try?

Probably not.

I ran into issues with it the last go-around with Jan whilst trying to debug S3 issues.

It turned out it got in the way of some scheduling stuff.

S3 will break the CPU affinity set up by that pinning, and it can lead to some unexpected behavior, and/or crashing upon resume.

I'd recommend against it.
