I’m not sure how the government would manage that in a fair manner; if SSDI is any indication, not very well. The SSA has a lot of outdated bias in its guidelines for providing aid.
At its root, anytime I see the government mandate something but foist the costs on the private sector, it is to pay lip service without actually ponying up the funds. Which is not only the politicians’ fault, because voters will vote for low taxes every time, even though the high level of services is not deliverable with such low taxes.

This also goes directly along side that retail workers are NOT permitted to have chairs at a register, because of the similar reason (standing constantly excludes disabled and pregnant folk). And somehow sitting=lazy unless it's white collar work. We're allowed to be 'lazy'.
