That appears to be a useful solution to part of the challenges in the domain.
I'm not sure what countries that spans (I'm in Australia) so there's perhaps scope for others to expand across other geographic locations.
There's also the "don't babysit me" aspect, a good number of elders are often slowly diminishing in capability and have no desire to be immediately shifted to a full guardianship when what they want is incrementally increasing trusted oversight that they are in control of.
