Unfortunately, it is not clear that the market cares enough

does not have enough practical value for Internet-connected
enterprises that they have been willing to incur any cost or

Totally wrong.
Many internet-connected enterprises have been willing to pay
extra money to have fixed IP addresses, and, worse, independent
global routing table entries for multihoming, to reliably
maintain the end to end transparency to reach their servers.
They do have practical values.
That's why the global routing table have bloated so much.
