Another way of looking at it is a simple logical test:

Is your content accessible, if you don't caption except when requested?

The answer is in one sense pretty obvious: No.

No captions = Not accessible.

Is there an obligation on people to identify as needing captions?

That's much trickier. The answer I give is that there are many who do not
even realise the benefit they get from captions, and are unlikely to think
of asking for them. There are also those who find it very challenging to
make the request - "I don't want people to realise that I can't hear half
of what they say", or the normal case in Spain, where I live, for english
interpretation, of "I don't want people to realise I don't understand half
of what is happening".

So while I think people *should* ask, I think relying on them to do so is
a straightforward failure.

Which is how I get to John's answer: No, it is not "acceptable". Assuming
your goal is to provide accessibility - or even assuming your goal is to
increase efficiency.

On the latter, as well as embarrassing auto-caption "fails", I would point
out that reading a transcript is, for many people, far more efficient than
listening, both in terms of time spent and ability to absorb the content.
So there is generally a significant productivity boost available too. But
that's a digression.

If your goal is risk management, that's indeed a question for your risk
managers. Companies and individuals do lots of things on the basis of
"I'll probably get away with it". But I don't recommend skipping captions
even on that basis, which should not be a big surprise.

In practical cases, looking at the real-world cost of captioning is
probably useful, before making a decision. Compared to most parts of video
production at a corporate level it's often surprisingly cheap. Sometimes
discovering that we're talking a few thousand dollars a year is enough to
convince the bean-counters that it is cheaper to do it than to think up
how to get away with not doing it.

and so the answer to that question likely resides more with your
