Now, perhaps that could use a note explicitly saying this also means

The part explaining subshells (3.7.3 Command Execution Environment) could
perhaps also use a mention
of that caveat, since it does mention set -e already, though in the context
of command substitution.
So it is clearly not a bug.
The shell -e or bash's errexit option is a problematic tools with hard
to understand side-effects.
I can't figure a use-case where a shell would appropriately straight
exit without any cleanup or fallback.
This feature deserves a bold disclaimer to think twice before using it
rather than explicit error handing.
