This isn't spelled out in the commit messages AFACT so let me ask..
Why aren't we reverting b5f0de6df6dce, then?
Feels like the best solution would be to have a separate type with
the flex array to clearly annotate users who treat it as such.
Is that not going to work?
My noob reading of b5f0de6df6dce is that it was a simpler workaround
for the previous problem, avoided adding a new type (and the conversion
churn). But now we are adding a type and another workaround on top.
Sorry if I'm misunderstanding. No question that the struct is a mess,
but I don't feel like this is helping the messiness...
