Transition also has "Universal Derailleur Hanger". Bike brands tend to mean "we have one derailleur hanger that works for all our bikes", which.... is a good step from where things use to be, with 3/4 of the bikes in each brands lineup requiring different hangers, and changing it year over year.
The important difference with the SRAM UDH is that the concept is universal across brands. Brands adopt/design around UDH, shops can stock ONE derailleur hanger SKU for any bike designed around the standard. The giant tackle boxes with "2019 Giant Reign" stickers next to "2004 Norco Shore" are gone.
As a bonus, everything will also be more consistent for derailleur performance. There's a fair bit of variation across brands with how the hangers are built, flex, shaped, etc. Think about any time you've swapped an RD across bikes - you may have had to adjust limit screws and b-tension, because the hangers are in slightly different locations. This is detrimental if you sell derailleurs, and are trying to maximize RD performance. Shimano kinda tried this a decade ago with Direct Mount, but it didn't stick.
