But with the alephs (ah sound with a beginning glottal stop), the hey (eh sound beginning with aspiration), the vavs (the "who" sound with beginning aspiration), and the yodhs ("I" sounds); as well as the punctuations (the colons, hyphens, and superscript dots, as well as commas which represent the tsere yodh).
I would think that those following the Noahide Law scheme but as ger tsaddukim would memorize these and not use the Gentile forms of non-Hebrew markings that tell us how to pronounce their nasty dog languages.
Also, you will note that Hebrew road signs, historical markers, and store fronts in Israel do not use vowel pointing, either.

From Wiki: "Protestant literalists who believe that the Hebrew text of the Old Testament is the inspired Word of God are divided on the question of whether or not the vowel points should be considered an inspired part of the Old Testament. In 1624, Louis Cappel, a French Huguenot scholar at Saumur, published a work in which he concluded that the vowel points were a later addition to the biblical text and that the vowel points were added not earlier than the fifth century AD. This assertion was hotly contested by Swiss theologian Johannes Buxtorf II in 1648. Brian Walton's 1657 polyglot bible followed Cappel in revising the vowel points. In 1675, the 2nd and 3rd canons of the so-called Helvetic Consensus of the Swiss Reformed Church confirmed Buxtorf's view as orthodox and affirmed that the vowel points were inspired."
