You're correct that potentially any field could be entered via
barcodes.  As I explained in my initial email, though, the point is to
provide a suggestion for fields that you *intend* to be commonly
filled with a barcode.

This is precisely the case that inputmode is *designed* to address -
*any* field could *potentially* want latin-prose, or numeric, or kana.
 The inputmode argument, though, provides a hint that the user is
*likely* to want to enter this input's value with a particular mode.
