I did some searching.

On 2017-06-17, Craig attached his "updated for 4.x" version here:
    https://sourceforge.net/p/backuppc/mailman/message/35899426/
This is the same message and version that I linked to above.

On 2019-04-11, Alexander Kobel endorsed it, but provided some caveats
about using it:
    https://sourceforge.net/p/backuppc/mailman/message/36636938/

On 2019-05-02, bac...@ko... (i.e., you :-) reported that it
emits (apparently benign?) error messages:
    https://sourceforge.net/p/backuppc/mailman/message/36655409/

I find no later version, in the archives, than the one posted
by Craig.

I did see the version that Mike Hughes pointed out, created by github
user phoenix741, here:
    https://gist.github.com/phoenix741/99a5076569b01ba5a116cec24a798d5f
The starting point of that code is identical to Craig's version of
06-2017, with the addition of a small patch that appears to modify
some ranges of attributes:
    https://gist.github.com/phoenix741/99a5076569b01ba5a116cec24a798d5f/revisions?diff=unified

With no comments in the code, and no commit log (do gists even have
commit logs?), it's a little hard for a layman to know what the purpose
of the patch is.  (Is it generally applicable?  Or did it only solve some
particular problem of theirs?)

So anyway, these are all the versions of v4-capable backuppcfs I've been 
able to find.

Needless to say, it would be great if someone would take that script and
take on a maintainer role.  (I don't have the perl skills, nor the necessary
backuppc knowledge, to do that myself.)
