Traditionally, one sets up a dist/configure or automake rule
that figures out where the lib is, and the software uses indirection to
determine the TG_LIBEXEX_DIRPATH or something.

This is only a nominal benefit. If I ship the integration branch
as the diff.gz, you have no conflicts to use the all the features
Now, If I want to try just topic F, it is easier with pure topic
patches. Trying just feactures E and H is also easier with just the
pure topic patches, though perhaps with some work.
I am looking at the common cases here. I posit the most common
case is to:
a) Want all the features (use the diff.gz integration branch)
b) Try a single feature (use orig.tar.gz and the pure feature patch)
Combinations of a subset of the patches are still relatively
easy, at he expense of perhaps needing some work.

*Shrug*. To get to this developers preferred mode of working,
there is redundancy in the feature branch + integration branch mode,
I just want to ship my preferred form of modification in the
This might not work for X.
But no technique is a perfect fit for all packages.
Where there's a will, there's a relative.
