I was also confused with the name suggestion as in one of the mail you
sent out later, you mentioned:
" Eh, too fast typing, obviously the other part of the name... node names
should be generic, so just "bus"."

That is why needed to confirm. To me now "cdx: cdx@4000000" makes sense.
Hope this seems correct?
