I'm a bit puzzled.  You're removing instructions from this file, which
were available since 2010.  I'm not sure this is feasible.  Wouldn't
that potentially break existing code?

Can you please explain the background why instructions, which were
supposedly available since 2010 are suddenly "unsupported"?
