What do you mean by "generally" here? Are there known exceptions or
are you just being careful to allow that there could be exceptions?

Whether a requirement is implementable is rather a different question
from whether particular client software intends to implement it.

Both iCab and Opera implement the expectation: "User agents are
expected to allow users to access long text alternative resources
indicated by the longdesc attribute on img." So the expectation would
seem to be "implementable".
