Sentence was written under the assumption that all .la files will be
shipped (as suggested by your question).

No; modules (which are non-devel files) can contain something like
| dependency_libs='... /usr/lib/libkickermain.la ...'
--> non-devel file requires .la file
--> .la files must not be in -devel package

When it would be only the small .la file in -devel, I agree.
But I have problems with shipping a useless file without a good reason
in -lib packages.

rpm would bark loudly about broken dependencies in these casees.

I know exactly one case where they are required: when software uses
This can be fixed easily by writing 'lt_dlopenext("foo")'.
Installing .la files happens probably only due to legacy reasons.

See above about lt_dlopen(); KDE (which requires .la) moved away from
