Do residential bathrooms designed for older adults need to have corner-located toilets?

The corner location facilitates the installation and use of wall-mounted grab bars. It seems to me that bowl-mounted bars have far more utility for most older adults in the sit-and-stand movements than wall mounted bars. Also, the traditional idea for the horizontal-wall mounted bars next to a toilet is to allow a person to execute a sideways transfer from a wheelchair. Very few older adults, should their situation demand the use of a wheelchair, will have the arm/hand/upper body strength to safely perform a sideways transfer.
What do you all think?
