This function should not be removed but improved; e.g. a check if
missing if a split package was removed and then automatically remove the
split package from the repo. This function ensures that the repo
contains the same as abs/svn.

We can no longer guarantee that a package in the repo was built with
the PKGBUILD in the svn/repos dir or abs. Or in short: you cannot use
abs to rebuild the repo.

It sure is. What you propose is just being more relaxed on integrity
and literally decouple the binary repos from svn. This is not a minor
straight forward change and should be done right. In fact I already had
some ideas about this. I could send a more detailed mail if wanted. In
short it repos like this:
* Use svn just for trunk (or other branches) but no longer try to "tag"
what is actually in the repos. Means removing the repos subdir
* Instead switch to a pure package based approach. dbscripts will only
know about single packages. (would still need an integrity check to
search for removed split packages)
* Improve makepkg to create source packages with every build. Should be
* Upload these source packages together with the binary packages and
store them in another repo
* If you need the pkgbuild of a package (e.g. for abs) just look for a
source package that corresponds to the scheme mentioned above
* Note that the db files is the only place where information are stored
in which repo a package exists.

These packages are a hack anyway. Upstream has different source
packages for every language. We collect them into one PKGBUILD and split
them again. There is no sane way to keep removed languages here. (and
also no need; if they were removed by upstream we should do the same.)
Summing up: We really should not try to support different versions of
split packages with our current svn repo setup. Instead we should
rethink the whole setup first as described above. Then we can easily
implement this in a clean way.
