Are PATCH .sdb's no longer work in Windows 10?

No matter what I try, my PATCH SDBs are being ignored in Windows 10. All other SDB's (InjectDll, etc.) still work fine.
Is this a known issue or am I doing something wrong?

I do not believe they work in Windows 10. See this blog: http://subt0x10.blogspot.com/ from Casey Smith

Interestingly, the sdbinst.exe utility still has the -p flag to install PATCH SDBs, suggesting that the support is still there, so I'm wondering if maybe just the format has changed or it needs a special tag, a signature (finally?) or something along those lines.

I've compared apphelp.dll on Windows 7 versus Windows 10. The Windows 10 version does not have the function SeiApplyPatch. This is what is responsible for performing the PATCH. It appears that Microsoft has removed this feature.

The sdb maked by sdb-explorer is no longer work in win10, but I found the EMET's SDB work fine in win10, So I made a same sdb file as EMET's sdb, it doesn't work also. It's confused.
I beleve that there is a way to make it work in win10.
