Another question is, why the fillborders doesn't check if the input is
writable, as suggested in doc/writing_filters.txt.

Because it request writtable frames.
Hey Paul, how is this managed?
I don't see something like "get writable frame".
It is at bottom.
Do you mean
     .flags         = AVFILTER_FLAG_SUPPORT_TIMELINE_GENERIC,


No, in here:

static const AVFilterPad fillborders_inputs[] = {
    {
        .name           = "default",
        .type           = AVMEDIA_TYPE_VIDEO,
        .config_props   = config_input,
        .filter_frame   = filter_frame,
        .needs_writable = 1,
    },
    { NULL }
};
