this is only relevant people who are masochistic enough to go beyond
`-Wall`. (note that at this warning level, there is plenty of noise from
Dune and other upstream dependencies.)
IMO the term "vanguard" expresses better what these classes are
supposed to do: level the ground for the cavalry. Normally this simply
means to create and distribute a grid object, but it can become quite
a bit more complicated, as exemplified by the vanguard classes of
ebos..
