I think embedded choices were in YANG 1 and hence this is not a new
issue specific to YANG 1.1. Please correct me if I am wrong.
I am personally fine with embedded choices if the semantics are well
defined so that implementations interpret them the same way. Have you
tested different tools?

PS: It is possible to write obfuscated code in almost all languages; I
think the question is more whether the regular common use of the
language is intuitive. A good language IMHO follows a set of
simple general rules; attempts to rule out constructions that some
people find obscure can turn a set of simple general rules into a
complicated collection of special case constructions that make
language maintenance and implementation a nightmare.
