Some publishers of English historical literature when correctly presented by authors with text containing these patronymics with the abbreviation point added, have simply removed the points arguing that this 'full stop' in the middle of sentences is confusing for the English reader, thereby wrongly embedding the abbreviated name as the real one in the readers' minds. This happened for example with the text of "Batavia's Graveyard" according the Cambridge educated historian Mike Dash, its author. This is the more reason to write the full name in the first place. The message therefore is simple: do not use abbreviated patronymics when writing, in English, about 16th and 17th century Dutchmen and nobody will be confused.
