[seL4] Will the codes in branch rt be merged into master

Hi, I got information from https://wiki.sel4.systems/seL4%201.0.0-rt-dev , the development branch for the seL4 realtime extensions. My question is that will the codes in branch rt be merged into master, and add some build option. If a working tree always not in the master branch, it will be very difficult to be managed.
