Thanks for looking into this. Forward compatibility is a good thing.

I agree that the boolean-string translating is a bit ugly, but to be
honest, I also don't not dislike the double negative in your alternative
solution. ;-)

I'm definitely fine with changing that header name if necessary, though.
Since that's an implementation detail of zope.testbrowser, it should be
nobody else's business, and your tests seem to confirm this -- excellent.

I don't have a *strong* opinion which serialization of that flag is less
ugly. I'm leaning towards the trunk one (no double negatives), but
either one is basically fine by me.
I've given you pypi rights for zope.testbrowser.
