Hello Nigko. I should have been looking for agreement from the start,
and now with your statement of the problem, I concur that without the
current implementation of `current-source-directory', it is hard not to
follow symlinks. But then again, the current current-source-directory
already does follow symlinks in nearly all cases, even in configuration
files, except apparently when called in weird ways like local-file,
maybe because of Guix’ code staging.
It is not consistent, but actually I do not know why `local-file', when
calling `absolute-dirname', takes this case of `if'.

Documenting this work-around is not enough; we would have to also
document the rationale that local-file is weird and inconsistent,
because current-source-directory is weird and inconsistent.
I believe making local-file usable with any symlinks is better, and
changing absolute-dirname used by current-source-directory achieves
that.
The other alternative is making local-file not use
current-source-directory.

Yes, macros are not necessary, because syntax-source, as used by
current-source-directory, is not necessary. Why does
current-source-directory use syntax-source? Perhaps it works even
outside modules.
Another reason against the other alternative.
