Thanks for reaching out! kata-containers does not expose any MMDS to
guest applications at the moment. There were discussions using it for
simple container data transfer (such as kubernetes secret map etc.) but
it is not implemented.

I cannot tell if there is any customer using it internally (If so, it is
time to speak out, please!). Other than that, I'd like to say that
please feel free to make breaking changes and we'll be glad to use the
refined APIs when needed.

Cheers,
Tao
