I can see the appeal of this, but it's too big a change for me. If I had
a vote, I'd vote against it.

Sorry? They're both grammatical in the current grammar, but {co'a na'o
broda} falls foul of what CLL says about ZAhOs coming last. Is that
what you meant?

And what that reflects is the tense model which I thought was the
official one (though I'm less sure now) and which is at least a
plausible one - you define (considering just time for simplicity) an
interval, then a subset of that interval with TAhE and PAroi, and then
how that subset relates to the event of the bridi(/seltcita sumti,
preferably, though apparently that does contradict CLL) with ZAhO and
PAre'u.

If you want to use ZAhO in a different way (as in your translation of
{co'a na'o broda}), then that's cool - as long as it's part of a general
scheme which gives meaning to this class of tenses ({ZAhO TAhE}, or
preferably {ZAhO (tense as above)}). That's all I'm saying, and that's
what I don't see happening, and is what I was clumsily attempting with my
JOI1 thingy.

I guess this is basically the prescriptivist-naturalist (is that what you
guys call it?) debate again - the alternative to prescribing an
understandable model for construction and interpretation of tenses being a
lawless breeding-ground for confusion and malrarbau, with people just
using the keywords to translate to and from lojban - rather than
translating directly to and from the spatio-temporal locations of events.
IMO. I just think we can and should do better.

Now whether we actually declare phrases which don't fit our models to be
unparsable or just meaningless, I don't see much matters. But having a
the set of meaningful words being easily decidable (by brains as well as
machines), such as is assured by making it part of the formal grammar,
would be particularly nice.

Hmm, same here. But how does that fit in with {carvi ze'a le ca dunra}
*not* being the same as {ze'a carvi}-with-the-winter-as-reference? I
don't see how you can reasonably make a special case out of ZAhO, with
it having a different meaning when part of an explicitly expressed tense
like the above. Whatever CLL says.

I think the implications of this lead to a contradiction of CLL and
common usage, but I can't seem to find the words to express it right
now. Sorry. I might try again later.
