Ah, a very different understanding of defensive use of a patent,
and one that I can see would lose force if there could be no
conditions on its use.

I was thinking more of the use of a filing to establish prior art
so somebody else later can't obtain and enforce a patent on
the technique that you're already using. Something along the lines
of a statutory invention registration[1], which used to be a thing
in the US, but now apparently is not, though any filed, published
application, granted or abandoned, can serve the same purpose.

That, I think, would still work.
