Seems a bit niche... 90 ADS results for "OVV quasar" 70 results for "optically violent variable quasar"

From the provided Wikipedia link: "OVV quasars have essentially become unified with highly polarized quasars (HPQ), core-dominated quasars (CDQ), and flat-spectrum radio quasars (FSRQ). Different terms are used but the term FSRQ is gaining popularity effectively making the other terms archaic. "

It sounds like FSQR is the preferred term: "Although the names OVV, HPQ, CDQ, and FSRQ reflect different empirical definitions, evidence is accumulating that they are all more or less the same thing."

There is a deep connection between FSRQ and BL Lac: "The main differences between BL Lacs and FSRQ are, to first order, that the FSRQ are more distant, more luminous, and have stronger emission lines." "BL Lacs and FSRQ are intrinsically the same objects..."

Frank Timmes, AAS High Energy editor, is in favor of adding FSRQ with the other terms (OVV, HPQ, CDQ) as NPTs.

Adding as child of Blazars.
