Because I for one want to see BY-SA strengthened in such a way this time that
it will be a stronger copyleft for non-code that the gpl is for non-code.

I for one do not see a source requirement as a non-Free requirement and if we
could ever pin down proper "source requirement" wording for non-code, I would
suggest we add it to BY-SA if it can be done in a non-onerous way.

I am cool with that. I certainly want to make it as easy as I can to let
others build on/from my stuff.

And if you never had latex yourself in the first place?

Oh but we may indeed be speaking of material objects. Now do you want to
limit
