Cannot create symbolic links on drvfs network share

Environment

Windows build number: Microsoft Windows [Version 10.0.19041.329] 
Your Distribution version: Ubuntu Release:        20.04
Issue in WSL2

Steps to reproduce

I have 2 PCs with same WSL2+ubuntu set up, and sharing my respective WSL home directories (set to C:\Users\MyUserName\WSL_home) as \\PC{1,2}\WSL_home
Mounting the remote home dir in WSL works fine (permissions, ownership, file & directory CRUD, symlink following), except for symbolic link creation.

$ sudo mount -t drvfs '\\PC2\WSL_home\'  /mnt/rhome -o metadata,uid=1001,gid=1001
$ cd /mnt/rhome
$ ln -s /mnt/c/Users/MyUserName nthome
ln: failed to create symbolic link 'nthome': Operation not permitted
$ touch dummyfile
$ ln -s dummyfile dummylink
ln: failed to create symbolic link 'dummylink': Operation not permitted

I have tried to mount local pc share (\\localhost\WSL_home) and do same steps as above, same outcome.

I have also tried combinations of running WSL as administrator or not, granting (or not) Symbolic Link Creation by policy, enabling (or not) symbolic link evaluations for remote to local & remote to remote symbolic link ; this on local and/or remote hosts. Same outcome.

Strace gist for the dummyfile -> dummylink example, with \\localhost\WSL_home\ mounted as /mnt/rhome

Expected behavior

(WSL) symbolic link to be created.

Actual behavior

Cannot create symbolic link on mounted network share.

Reproduce the reported mount and ln commands against a drvfs network share, then review the linked strace gist for the failing operation. Investigate the WSL and drvfs handling involved; done means symbolic links can be created on the mounted share under the reported configurations, with coverage for the demonstrated cases.
