That release branches make sense in some circumstances does not mean one has to take all of 'git flow' on board. This is the problem that the comment you are responding to notes. One should design a branching strategy depending on what one needs to do and not do things because one has a branching strategy.
True but I have seen people claim TBD should be used in all cases and I was trying to get some insights on how people use TBD for mobile apps as using release branches is not TBD as well.
I love TBD. But it has its places. For mobile apps I've used (and would use) release branches. You have a hard requirement on the way that app stores work.
You can still do TBD for most of the development of new features, though.
