I'm sure LittelFuse [Zilog] would keep making them if it were not for the foundries wanting to move away from producing old (& more importantly) large geometry parts.
Honestly I'm surprised it has taken this long.
There are still large stock quantities around at proper distributors for the time being.
After that, if you need new parts, it wouldn't rake much to put a z80 core into a small flash based FPGA (such as the Lattice ICE40 or Gowin LittleBee GW1N) and add some level translators
for 5v signalling all in the size of a DIP40 package for less than you can buy a new Z80 currently. Same goes for the peripheral IC's such as the PIO, SIO etc.
