no, seems like they (devs/mods) dont see it as a problem. for me, it gets worse - i have to switch the input now multiple times until the odroid wakes up. multiple means > 6-10 times. pretty annoying.
i also have sometimes the problem that when i press a key on the remote, it got send twice or sometimes three times. i am sure its not a problem with the remote but with the CEC because the remote works like a charm when i use the tv functions. and i have 2 remotes, both have the same problem with kodi/odroid. and when i use my tablet with kore, it works as expected. so i am very certain its a CEC problem.
edit: just noticed there is progress going on at this thread: CEC not working
