Ok, i've misinterpreted it.

Yes of course, a repackage should not rebuild anything.
The suggested separation of building (function build) from installation 
(a function in splitinstall array) would achieve that for you.
The repackaging would just overwrite the data (by installing it) and the 
vars for your package (pkgname, deps...) and repackage it.
The normal workflow after an error would be to fix it inside of your 
PKGBUILD file instead of in the pkg directory anyway.
Also it wouldn't work without altering the variables to get 
splitpackages out in a repackaging case the way you would in a normal 
build without running the install function which alters the pkgbuild 
vars for you.

Some nice cornercases would be that you could list all dependencies you 
need to build all of your subpackages in your main definition on top of 
And you can break down to the ones really needed for a splitpackage in 
your install function.
Think about a package php-common and splitpackage php-mysql in case of 
the dependencies to (lib)mysql...

The point of this suggestion was to make it possible to reuse allready 
working and tested code as much as possible.
But it was just a proposal from my point of view at that time.
After some thinking i came to the conclusion that it would be better to 
have all splitinstall trees around after a run without "-c" to check if 
the dependencies are correct.
So let's do it that way.
