While the battery remains a standard CR2032 coin battery, and the mounting mechanism is not completely inaccessible, due to this misleading language in the manual and obfuscated location of the battery, it is a blatant attempt to make the mainboard obsolete when the battery dies.  Replacement requires service from an experienced technician, leading to more device turnover.  For 40 years of mainboard design, replacing a CMOS battery has required locating the battery on the face of the mainboard, pressing a clearly marked tab and removing the old battery out of the standardized component clip slot, and putting a replacement one in its place.  There is no reason to have changed this.
