BlueZ supported features/profiles

I am looking for the information on what profiles or features are
supported by BlueZ.
There are 2 places that I can find such information, one is in the
BlueZ official website and another one is in the release package from
a file called supported-features.txt, it looks to me that the text
file is better with more details but could anyone here please confirm
that I can rely on it?

Also, if the features or profiles are not listed, i.e. TCS-BIN
protocols, then is this not supported?
