What linux distro support SMR HDD by file system?

According to this Seagate presentation there are some ongoing (?) efforts targeted toward modification of ext4 file system introducing SMRFS -EXT4 - support of hmHDD. The goal is to provide layer that will hide specifics of ZAC commands from applications (I believe). There is also this document that claims that "As of kernel v 4.7... hm drives are exposed as SG node - No block device file". What does it mean? maybe these document are outdated and ext4 (or other common linux file system) has been added support for host aware HDD. What linux distro support HMHDD by file system? If such support exists - What steps are needed to get HMHDD up and running without changes in applications (where file system hides all specifics)? General applications like DB are my concern - not log style. Also there is such video (SDC2020: Improve Distributed Storage System TCO with SMR HDDs) that claims that starting from 4.10 linux kernel f2fs supports drives already - did you used such approach? Maybe f2fs is not best match for random operations but I hope f2fs can fulfill such tasks with acceptable performance (where reading is dominant)
