Oh, I didn't know about that option. Though it would make more sense if
the block size was specified in terms of container elements rather than
bytes.

Oh #2, I can see there is block_size, but it is not documented as an
acceptable option for deque_options. Is it actually supported?

I thought, the user was supposed to specialize deque_block_size for
their value type. Given that there are container-specific options for
this purpose, you can consider my request fulfilled, and sorry for the
noise.
