The display details can vary broadly depending on the application and
the context. Feed readers are diverse enough that it simply does not
make much sense for the bidi draft to specify any requirements as far as
alignment is concerned or even appropriate levels of embedding. The
most the spec says about alignment is that implementers MAY use the same
alignment rules as HTML but no requirements are specified.

Doesn't dir="rtl" generally result in blocks being
right-aligned instead of left-aligned? At least this
is the case in HTML.

Possibly. I bet James would be able to answer better than me. I would
think that the default alignment would depend heavily on the user
interface of the application and the user's language preferences.
My understanding is that directionality overrides are primarily focused
on the correct rendering of characters that are not stringly LTR or RTL,
like punctionation, when they appear between strongly LTR and strongly
RTL letters. The W3C ITS recommendation has a few examples in its test
suite that demonstrate its BIDI overrides, and those examples all deal
with punctuation between English and Arabic text.
