Assuming you are referring to the following:

which is accompanied by the following warning:

The details and summary elements are not well supported by browsers, until

I do not see how this advice is fundamentally flawed, and it is similar in
content to what I would have suggested for longdesc advice i.e. yes this
feature can be used but be warned you will have to do some extra work to
ensure the feature is practically usable as its support across is uneven.

If this is the only example of what you consider a 'fundamental flaw' in
the advice in the doc?
