To clarify: is "local foo=bar" policy-compliant or not? (If not, *sigh*.)
To the best of my knowledge, no, it's not compliant. The relevant section reads:
<snip>
* `local' to create a scoped variable must be supported; however,
`local' may or may not preserve the variable value from an outer
scope and may or may not support arguments more complex than
simple variables. Only uses such as:
fname () {
local a
a=''
# ... use a ...
}
must be supported.

As "foo=bar" is an argument "more complex than simple variables" and the
example explicitly shows the use of local to declare the variable followed
by assignment to it, my reading of policy is that "local foo=bar" is not
permitted.
