This might be fixed on master already. Any chance a new version of cssnano can be released?

Thanks for the report.

Yes this has been fixed in the master and the output is .transform-parsing{transform:translate3d(0,0)}

About the release, I hope it will be done soon.

I have created a kind of workaround in which you can use the updated master code using cssnano-nightly.
Though I will not recommend that for production as I made that yesterday itself so may notice some bug.

Fixed in 5.0.0-rc.2
