Right, and it also happens with "--only-input" (part of "--parse")
"--only-input" is documented as follows:
Output only trailers that exist in the input; do not add any from the
command-line or by following configured trailer.* rules.

Would that option also be set for the parsing done by "%(trailers)"
pretty format specifier?

I'm also mainly using in reading trailers (mostly with pretty format
"%(trailers:key=x)") and then these convenience shortcuts doesn't really
seem helpful, they rather add a small risk of mangling my data. Not that
this has caused any problems for me in practice.
