Update:

I now have the spec for the Epson TWAIN capabilities and the feature I 
was referring to above does have a name:

ICAP_UNDEFINEDIMAGESIZE                        MSG_SET to TRUE to apply 
auto size dropping

And it is implemented in Epson Scan 3.66 or later.

I don't really have words for my lack of understanding of such a 
feature, but anyways...
I'll try my best to get that into the backend.

The following is also a candidate, since it seems to cause the same 
behaviour:

ICAP_AUTOMATICBOADERDETECTION        MSG_SET to TRUE to apply auto size 
dropping
