The one place a self-laid broadcast form receives the caller's options: every
compose returns its message's own fields through it, so no form can drop
sendSilently, isXTransportForward, isShhMode or extras.
is_x_transport_forward, send_silently and is_shh_mode=1 go right after
action (at the front when the form has none, as the GIF's), in that order
— the reply's recorded order for the first two; the disappearing mode is
recorded on no self-laid form.
carries names the options the message's recording always carries, with the
value it sends when the caller gives none (the reply's false pair, the
photo's and the share's is_x_transport_forward=false); an option neither
given nor carried stays out, as the recording has it.
extras go where the generic form puts them: before
offline_threading_id (at the end when the form has none).
A form that lays one of the option fields itself, or extras that name a field
the form already holds, is a defect of the message's declaration: a second
writer of an option, or a rewrite the extras must never make.
