Yes. In reality anything big is going to go up on an HTV and will never
pass through the station interior.

With the demise of the shuttle, have ESA and JAXA made commitments to
increase their originally planned launch rates for ATV and HTV
respectively ?

I remember reading that ESA had originally commited to a fixed number of
vehicles launched over the lifetime of the station. (since it was
expected that the Shuttle would remain the workhorse for cargo haulage).

Are there now commitments for regular launches at fixed frequencies ?
