IMHO, the problem with this form of "weak" copyleft is: what if your
code is incorporated as part of the larger work so that the boundaries
are not so well defined?
I mean: your code could, for instance, be included inside one source
file of the larger work, blended with other parts of the larger work.
At that point, having access to the source for your code under its
original license terms (and nothing else) would be of little or no use,
in order to have freedom on the larger work.
Of course, it would provide freedom on your original code, but that
would be guaranteed (almost) equivalently by a simple non-copyleft
license (such as the Expat/MIT license), as long as your original code
remains available from other places under these non-copyleft free terms.

In other words, you want to maximize compatibility with other copyleft
licenses and still have a copyleft license...
I think these two requirements are _very_ hard to satisfy at the same
time; it could be that they are actually incompatible with each other.

I share this desire for a license written without distinguishing
between different kinds of software.

The GNU GPL is not far from being such a license: it talks all the way
about a "Program", but defines this term as "any program or other
work" (GPLv2, Section 0.) or as "any copyrightable work" (GPLv3,
Section 0.).
Hence you may think "Work" whenever you read "Program" in the GPL text.
