This is a good enough solution, IMO.

This would be slightly better, indeed.

I'd like to reserve optional parameters to more important customizations than
this one.

This is not possible, because there may be multiple gnulib-tool invocations
in the scope of a single configure.ac; one of the invocations may import
test module while the other doesn't.
I'm applying this:

Allow the user to avoid the GNULIB_TEST_* macros.
* m4/gnulib-common.m4 (gl_ASSERT_NO_GNULIB_TESTS): New macro.
Suggested by Paul Eggert.
