No, I didn't know it. It will help me to understand the problem, but I
will need some time to reed.

That is the implementation side. In ODF1.2 file format, shapes have
child <text:p> which has child <draw:frame>, which has child
<draw:text-box> or <table:table> a.o. So "complex" text is possible
without anything in addition.

AFAIK draw:engine is not

Till now it is not obvious to me, why this information needs to be in
the file format. Couldn't it be detected when parsing on opening?
And would LibreOffice not show the <text:p> element of the shape, when
it is "complex" but not marked as such? You cannot expect that another
producer will write such attribute, because "complex" shape text is
already possible yet, without having such attribute.
Do you have, by chance, an ODF document where

No, I do not know, whether any application writes the attribute
draw:engine. I would expect it for MS Office 365 or MS Office 2013, but
I haven't got one to test it. But from its description, "The draw:engine
attribute specifies the name of a specific rendering engine that can be
used to render a custom shape." it would do exactly what you want -
only, that it is currently only usable for custom-shapes.
And are you really going to implement the new engine for arbitrary shapes?
BTW, the example
from the blog post is not valid, because <table:table> is not allowed as
child of <draw:custom-shape>.
