dislocker package broken, fix in 'sid'. How long 'til in backports?

[Michael Bonert <michael.bonert@utoronto.ca>]

I am running Debian stable (buster).

The dislocker backport doesn't work for files from Windows 10 1903 (as  
noted here:  
https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1710592.html  
)

I noted that the latest version of dislocker in 'sid' (unstable) is  
0.7.1-5 ( https://packages.debian.org/sid/utils/dislocker )

The release notes for 0.7.1-5 (  
https://metadata.ftp-master.debian.org/changelogs//main/d/dislocker/dislocker_0.7.1-5_changelog  
)
say:  "Added new patches to support Support Windows 10 1903 and fix  
build issues.Thanks to haobinnan <haobinnan@gmail.com>" - sounds like  
exactly what I'd like to have.

How long will it take for 0.7.1-5 to appear as a backport?

Thanks,
Michael

PS -
I will trying making my own backport (  
https://wiki.debian.org/DontBreakDebian /  
https://wiki.debian.org/SimpleBackportCreation ) but prefer to avoid  
that... if isn't too long a wait.
