In my understanding, ERT is a last ressort. There are a lot of syntax
changes that are easily converted back to the old format. This is why
a switch like ::

  > elxyer --lyxformat
  221
  
could be a help.

This we agree on.

Did you check this new requirement with all LyX developers when
proposing native LyX->HTML export? I can imagine that some would think
it meant "Richard will be expected to make sure this works properly
with HTML export."
(In any case I am very glad, that math support is already present in
LyX...)
