Different methods have different amounts of specificity in the way they're defined. With "X/Y" for example, any desired pattern of microphone can be used with any desired angle between their main axes, as long as both microphones are directional, have the same pattern as each other, and are essentially coincident in the horizontal plane. The ORTF method, on the other hand, has an extremely specific definition, and if you vary it, it's no longer ORTF.
The ORTF method was invented using Schoeps microphones of the M 221 series, back in the vacuum-tube era. The ORTF (a/k/a Radio France) was always one of Schoeps' most important customers and still is today. When the "Colette" series of solid-state mikes was introduced back in the 1970s, an ORTF mounting accessory called the STC (for two cardioid capsules on Colette cables) was soon introduced. Then they introduced a single-body stereo microphone called the MSTC with the same configuration. I bought serial number 012 of that model and used it for many years.
Schoeps offers stereo bars based on the STC, but designed for their MK 21 and MK 22 capsules or equivalent CCM compact microphones. Of course the ORTF method was the point of departure for these, and the stereophonic recording angles that result from these setups were chosen to be the same as that of ORTF, or just a bit wider (on the assumption that one might mike a bit more closely with the less directive capsules). But there are no specific names that are at all widely accepted for those setups. I think Schoeps' literature may say something like "reminiscent of ORTF" somewhere, but that's as close as they ought to get IMO.
