The bugfixes you said are not really something fixed by Phobos, IIRC those can be fixed using INI editing.
Without modifying the game some occassional bugfixes are applied anyways. Among those are elevation overshooting bugfix (not very visible ingame because of artillery not using arcing projectiles in vanilla), some units "dying" multiple times because of damage applied to them during dying, maybe some else.
This is like 2% of Phobos though. As said, this is mostly a tool for modding, so to use most features you need to modify the game's INI files.
