Ok.  Reading through the bug (comment 53) it looks like Intel's take on
this is that it will simply not be needed long-term.

How about adding it to OvmfPkg/Include/Protocol/MemoryAcceptance.h then?

It surely will be very useful short-term.  If it turns out that lazy
accept support indeed becomes a standard feature we might drop this
in 3-5 years.  Or promote it to MdePkg should that not be the case.

take care,
  Gerd
