Just to say this isn't true, as the RPi2/3 does support H.265.
The RPi2 can play H.265 720p content without any issue, and with moderate overclocking can also playback H.265 1080p content (up to a bitrate of about 10Mbps). This actually makes a lot of H.265 1080 content quite playable on the RPi2. With the RPi3, it's usually not necessary to apply any type of overclock to achieve good H.265 1080p playback.
OK, I should have written "will not reliably play all H.265 content". I tried quite a few Handbrake encoded H.265 videos. With the recommended overclocking on RPi2 I observed stuttering, audio sync issues and artefacts at 2.5 Mbps and below. The point I am trying to make is you can´t put this into your living room and rely on enjoyable playback of an arbitrary H.265 source. So no "wife acceptance factor", for my wife "quite playable" is not enough.
