Sure, the documentation doesn't explicitly say that. But it also
doesn't say that pipelines are composed of pip

Yes, you can make the case that compound commands are pipelines, and,
according to the grammar, they are, but their status is always available
in $?, and they never have more than one status value.
In other words, this was a design choice?
Yes.

Moreover, bash accepts e.g.:
! ! false
How can you parse that, without a pipeline being a command?
Note that this is not posix, though bash accepts it even with --posix.
I implemented it that way because the original proposal

a COMMAND is a WORD

This needs to be corrected to note that compound commands that are not
one component of a multi-command pipeline do not cound as pipelines for
setting PIPESTATUS. Exactly which compounds commands don't set
PIPESTATUS needs to be made clear as it's not

FWIW there's still a use-after-free with something like:
HISTFILE= INPUTRC=/ bash --norc -in <<< $'X\n\cPX\cR\n!\e3X\e^\n\cP'
Thanks for the report.
